When rebuilding a raid there is always a good chance to Lose the raid altogether. In your case the likeliness is even higher as you have two drives showing issues. Save your content before you go ahead!

Yes, that could happen (due to increased load on the remaining discs during the RAID repair). But I guess Peter is now on his own.

I don't remember in which software version the Dolby was enabled to fix RAID issues by itself. Before, you had to do it manually. But as Peter wrote, he changed one drive before, so he probably knows what to do.

At least it seems he just ingested the StarWars 8 dcp, so, worst case, he would need to setup the system from scratch and create a new RAID with his 4 new discs, and he'll be able to reingest that flic afterwards and be up and running again within a decent amount of time. In that case, I just hope he'll be able to source a setup disc for the DSS100.

I have picked up 2 drives and another two will be available in the morning.

I actually have a show on Thursday night (tomorrow) so am just hoping I can successfully rebuild the raid by replacing the faulty drive. Drive 4 has some issues but it still allowed the show to run last night.

I guess I won't know until I put the drive in and reboot the server. Fingers crossed!

Chances are that the fourth drive will not fail completely, as it is relatively new. Drives with bad sectors can live for years. But honestly, that is somewhere between a vague hope and wishful thinking.

Take your time, and yes, fingers crossed.

In the long run, it is probably not a bad idea to have your own CRU drive to make backups - you will be able to use the same drive with the Doremi as well.

Peter will need to register on dolbycustomer.com if he hasn't already. Once he has an account, he'll need to open a support ticket and ask for a clean install ISO image file for the software version he wants. Once he has it, it's a case of burning that image to a CD, putting the CD in the DSS100's drive, and rebooting the server.

Even before he does that, he can look up the serial number (four digits) of his DSP100 here, to see the latest version of the software his unit is entitled to without an upgrade license and KDM. It'll be the final version that was released while his unit was still under warranty, which may be a more recent one than the 4.3 variant he's currently running.

An update KDM for the DSP100 will be needed. If he wants to install a more recent software version than Dolby's site is currently offering him a KDM for, he'll need to buy a license through a Dolby cinema products dealer in his territory.

However, please do check that the projector supports Cinelink II TLS before trying to upgrade to a more recent version than 4.3. I have a vague recollection of Steve or someone writing that the DSP100 can be downgraded back to 4.3 from a later version if necessary. That certainly isn't the case with a cat862 media block in a DSS200: upgrading it beyond 4.3 is a one-way ticket. In any case, I'd suggest checking out the TLS situation first, and if in any doubt, clean installing 4.3 again.

Well, I swapped out drive 3 and rebooted the server.The system then showed drive 4 as drive 3, however the rebuild RAID option was no longer greyed out so I ran it. After 2 hours I had 4 green lights and a healthy RAID. Drive 4 still shows the 7 reallocated sectors that it has since I put it in over a year ago.That will be the next one to change and then one every few days until all four are replaced.

I assume that I can just perform the same action for each subsequent drive: power off the server, replace the drive, reboot and then rebuild RAID. Although there are no longer any errors I assume that it will rebuild by virtue of a new unformatted drive.

I am going back later to test the weekend shows so hopefully Star Wars won't wreak it's revenge!!

By the way, the projector is a CP2000 ZX, my mind was obviously elsewhere. It is a nice projector, reminds me of the NEC a bit.

I did try to register with Dolby but was knocked back. It would seem that being a cinema owner/operator does not qualify one for an account.

It sounds a little weird that a DSS100 can finish a rebuild process in just 2 hours. Does the RAID status says "healthy" on the Server (if memory serves) page? I would also not reboot the server once a drive has been replaced. Next one, remove the bad drive, wait till it's identified as missing, plug the new one, wait till it's identified as present and start the rebuild process on the same SERVER page I mentioned - unless it starts automatically.

This is an outdated version of the DSS software. Not all Dolby software versions had automatic RAID Repair, someone with deeper knowledge about 4.3 should chime in.

Leo - Dolby is picky about which people to allow into their customer portal. Don't know why, but typically, all non-US applications from ordinary endusers are refused.
With 500GB drives, a repair may indeed go this fast I guess. While it's still an outdated server, the RAID controller does the job all on it's own.

Peter - yes, go on like this. Give the system enough time to recover, I'd say one drive every 1 or 2 days. It's up to you wether after some time then you source the necessary setup CD for a clean install to increase the RAID size, or if you simply leave it that way until you receive the Doremi. Would you mind having a look at the drive you changed, the manufacturing date?

In my previous job, as a rank-and-file projectionist, I was allowed to register and download updates for my DSS200s. But I was in the US. Strange - I wonder why they don't mind American end users updating their servers directly, but don't want end users in other territories doing so.

If I were in Dolby's shoes, I'd want as many units in the field running the current software version as possible, in order to minimize both the number of helpdesk tickets caused by people running outdated software versions, and the reputational damage that end users being affected by the bugs in older software versions risks causing.

I don't know why it should be considered weird.The manual suggested an hour or more to rebuild the RAID. When completed the RAID status was healthy All the content I tested afterwards ran fine, including Star Wars VIII.

Marco - are you saying I should remove and replace drives whilst the server is powered ? There are actually no "Bad" drives anymore, replacing the 500gb drives with the 1tb ones is more a precaution as this is now two of the original drives that have gone bad, so the idea is to get in before the other two die. Why do you say I should not reboot the server once a drive has been replaced? (if you just mean immediately after replacing I did not do that and did not intend to until I was ready to replace the next drive.)

Carsten- I will check out the drive that I removed for the date. Do you agree that I first power down the server and then remove the drive and replace it with the new one, or remove the drive whilst the server is on and wait for it to complain?

I'm not sure if I am going to re-install the software before the outdoor season ends as there really is not enough time between shows, apart from the fact that I don't know where to source it. If I do go to the Doremi, I can perhaps re-use the new drives, which means I will end up with a spare as well.

Peter - you should listen to Steve on that, although in principle I guess it makes no difference wether you shut down or do it with the server running. Some whacky drives may actually die when powercycling, so, in case one is already on thin ice, it may be advisable to not power them down. The Dolby server is built to allow hard drive hot swapping. One of my early Dolby manuals suggests the server to be shut down when replacing drives, while a later revision allows a change to be performed while the server is running. The early manual also has a passage on RAID repair to be performed manually after a reboot in RAID BIOS, while the later manual explains that the rebuild is performed automatically after drive swap. This later manual is for software version 4.2, while the earlier one is for software 4.1.2, so, you should be safe running 4.3.5.9.

Again, I myself have NO personal experience with an DSS100. I am not so picky about powercycling servers - never had a disc die during a powercycle, so, personally, I WOULD power down the server before changing the disc, but you don't have to follow that.

Do you power down your server daily, or do you leave it running over night? Note that there is a difference between actually powercycling and a 'soft' reboot (Ctrl+Alt+F1 followed by Ctrl+Alt+Del).

Carsten- When I first took over the cinema it was the custom to power down every night, including the projector, and cold re-boot every day.

When I replaced the projector I went to leaving everything on, except the sound processor and amps, and also put the projector in standby mode.

I guess there is an argument for both methods. Perhaps the constantly spinning discs are finally starting to show their age, hence the problems I have been having.

We've always hot plugged these drives as they are certainly capable. We do it overnight so there is no chance of glitching by doing it during the show.

Sam -
I hot swapped another drive (the one showing 7 reallocated sectors) last night after the show and left it to rebuild the raid. After removing the old drive the system recognised the missing drive as degraded and after putting in the new drive I was able to start the rebuild.

Carsten -
The date code on the old drive is 10353 which, depending on the decoder one uses, is late February 2010.

I made up a 20 second clip yesterday to include in the show and ingested it. When I went to test it the Show Player lost communication again and I had to reboot the system. I did not try again, and left the clip out altogether and the show ran faultlessly ( apart from young kids jumping on the deckchairs, breaking a chain fence, tearing branches off the trees, and one even thought it funny to steal a padlock from outside my bio box. All the while, the parents just ignoring them).

They sound like little angels. I recently answered a phone enquiry asking if we sold screen repair kits, "...you know, like the ones for bicycle tires, with, like, a white patch and some glue." It turned out that some kids had been running around in front of the screen while Star Wars was playing, adding some live action to the light saber scenes by waving blow torches at each other. The flame from one of them went through the screen.
