Author Topic: Doremi not rebuilding Raid Steve Moore Expert Film Handler Posts: 211 From: Leeds, West Yorks, UK Registered: Apr 2008 posted 01-28-2014 04:49 PM                     Well thanks for everyone's help so far, however the saga continues. I did the 200 miles trip today to our cinema armed with a 2nd Hand identical Hitachi drive, which I had tested and then wiped the MBR and also an brand new Western Digital Doremi approved 1TB drive. I also took new SATA leads. I swapped out the leads, booted the server, no change. I followed the Doremi "repair" process which takes drive "B" out of service, swapped the disk, let it mount that drive and it said "The disc replacement has been successful - The raid is rebuilding" and a green tick However when you go back to the diagnostic tools, the Raid says it is degraded and no drive info comes up, nor does it say rebuilding raid and a % done Then I tried removing the Hitachi and swapping for a Doremi approved Western Digital BRAND NEW sealed 1TB drive and did the same process and again it said successful however it did't actually rebuild the raid again. I looked in the Bios and also did a detailed report which i uploaded to Doremi and received the report back. It did claim it could see either of the new discs with correct serial numbers. However in diagnostic tools a yellow dot and degraded Raid status. After all that went into drive manage and it said the drive "B" operation not permitted - Device already disabled I have a photo (not too clear of the screens if that helps Sorry that was a long one. I'm a bit stuck now. Just out of interest, could I power off the server and fit three brand new matching drives, reboot and try build a raid to see if it can do that. Then if that didn't work simply power down and put the three original drives back in and be back where I was; or would it need to re-register the old drive, so to speak, thus possibly rendering them useless. Sorry that was a long Post, but any help would be appreciated.  |  IP: Logged Danial Simmonds Expert Film Handler Posts: 107 From: Kota Damansara, Selangor, Malaysia Registered: Jan 2008 posted 01-28-2014 09:56 PM                        That's weird i never encountered this yet. Anyway, replacing all 3 hard drives with identical ones, you can reinitialize the Raid, but this would make the server start fresh with no content in it. If it doesnt work in the GUI, you could try to reinitialize using the terminal code sh /doremi/sbin/reinit_raid.sh Refer to the installer manual it will have the instructions there. reinitialize is not a raid repair.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 01-29-2014 12:18 AM                     Assuming you have a TMS or the content backed up somewhere, really your best bet is to just re-initialize the raid and be done with it. Just back up your files first because they WILL be gone if you do this. MENU / SYSTEM / TERMINAL Type: su <ENTER> Type the super user password which I will not post here <ENTER> Type: sh /doremi/sbin/reinit_raid.sh <ENTER> After a 10 second countdown, enter raid size “3” The script will check disk status, size coherency, shut down services, etc. Let it do its thing until you reach “raid re-initialized”. Type: more /proc/mdstat <ENTER> Verify md1 = active raid 5 Verify md0 = active raid 5 MENU / DOREMI APPS / DIAGNOSTIC TOOL / Storage folder Verify all 3 hard drives are green. At the top of the screen “/data” and “/opt” will typically be orange. After several minutes a popup will appear “the RAID partition is now healthy”. You may now re-ingest content.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 01-29-2014 08:11 AM                     Not exactly sure wether I really understood the procedures and timing involved - but it is natural that RAID repair will take quite a long time to finish, and for this time RAID status will still have to be degraded. If you don't care about content on the drives, go ahead as the others advised and reinit the RAID completely. If you do care, insert the DOREMI supported drive, reboot, and try another repair and give it some time to finish (over night). Take your time and read the manuals. - Carsten  |  IP: Logged Gary Benn Film Handler Posts: 23 From: Leeds West Yorkshire Registered: Sep 2013 posted 01-29-2014 08:15 AM                     Carsten, Thanks for your reply. When the raid is re-building a drive the status should change from degraded to "Rebuilding 33%" where the % being the percent completed. This is not happening in Steve's case.  |  IP: Logged Steve Moore Expert Film Handler Posts: 211 From: Leeds, West Yorks, UK Registered: Apr 2008 posted 01-29-2014 12:07 PM                     Thanks for everyone's suggestions. Will have to make a return visit and further investigations. Will update you with any news. If anyone else has further thoughts I'd appreciate it. Brad- sorry for the double post; as I posted my PC hung on the original thread (twice) so I thought I would restart. As it happened it did post after all. I wont do it again!  |  IP: Logged Amanda Mundin Expert Film Handler Posts: 122 From: Belper, Derbyshire, UK Registered: Sep 2005 posted 01-30-2014 04:23 AM                     Our diagnostic tool screen looked like the 2nd photo recently, it had no information next to Device Model, Serial Number & Firmware Version the same as your picture, and when we tried to do a RAID rebuild it went through the rebuild menu and gave us the green tick like your 1st photo, but did nothing, and didn't bring up the rebuild (%). We switched the internal SATA cable to an old yellow one, rebuilt the raid with the existing drive and it has worked since.  |  IP: Logged Steve Moore Expert Film Handler Posts: 211 From: Leeds, West Yorks, UK Registered: Apr 2008 posted 01-30-2014 12:02 PM                     Thanks, Amanda, upon my return perhaps i will try both the original cables and get some more new ones too.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 01-30-2014 08:43 PM                     BTW - there is a nice and complete overview of all Doremi RAID conditions and how to solve them in this training-pdf (RAID issues from page 254): http://support.doremitechno.org/images/Portal/Cinema_Players/Resources/doremi_training_slides_20121121.pdf - Carsten  |  IP: Logged Steve Moore Expert Film Handler Posts: 211 From: Leeds, West Yorks, UK Registered: Apr 2008 posted 01-31-2014 11:02 AM                     Thanks, that helpful Carsten.  |  IP: Logged Steve Moore Expert Film Handler Posts: 211 From: Leeds, West Yorks, UK Registered: Apr 2008 posted 02-08-2014 03:22 PM                     So the next step in this saga is a return visit to the site this week, armed with three brand new doremi approved drives. So just to confirm with people who have tried this. All i need to do is swap the drives out, rebuild the raid and re-ingest content, right? All the macros, settings, I.P. details and 3D setting etc will still be in place as before? I do plan to do a backup of all those to a USB stick too (as I know the normal backup in stored on the RAID) Rebuilding the raid I presume automatically re-creates the two partitions the(md0/data and md1 /opt) itself?

The macros, network settings, controlview stuff, and probably more are on the flash drive and don't get deleted. I'm not so sure of the playlists but I think they are OK as well.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 02-08-2014 04:20 PM                     Steve, see my post above.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 02-08-2014 08:18 PM                     You can initialize from diagnostic tool as well, or use the terminal command - same result. The only thing to keep in mind is that it will take maybe 5 hours to complete initialization. If a site tech has to do this I suggest they start it after the last show, it will be done in the morning and if there's a problem then time remains to do it over.  |  IP: Logged Steve Moore Expert Film Handler Posts: 211 From: Leeds, West Yorks, UK Registered: Apr 2008 posted 02-09-2014 12:58 PM                     Trouble is i am projecting at my cinema the night before, so going over early next day and possibly stopping over. the plan is to put new discs in so if something does not work and can revert to old ones instead. I will be doing through the diagnostics, Brad, unfortunately the installer has changed the su password from the normal one and wants to charge a fortune to change it back. I can get into diags with admin password.  |  IP: Logged
