July 17, 20232 yr I had this start after a power surge that my UPS didn't correctly handle (was low battery, so power cycled). That has been addressed, but no matter what I've tried each reboot the parity-sync gets to 100% and then sits there for days. This last round I tried a new config and a full parity rebuild. It is reporting that it found 0 errors, but I am not sure what to try now. I have tried to pause or cancel, but it appears to be unresponsive to those two actions in this situation (using the GUI). While this parity rebuild was running I addressed all of the known issues I could see in the fix common problems plugin. Thank you! tower-diagnostics-20230717-0753.zip
July 17, 20232 yr Community Expert Solution I've seen that before with those Dell RAID controllers, unfortunately no real solution that I know of, other than using a different controller. You also need to check filesystem in disk1 and change from mcvlan to ipvlan.
July 18, 20232 yr Author Docker was set to use mcvlan, but I've stopped Docker and changed it to ipvlan before posting this, but I think it is seeing that in syslog so need to reboot for that change to take place. I'll check filesystem on disk1, have been waiting to reboot so I can get into maint mode and try that. Will report back. Thank you!
July 26, 20232 yr Author Repaired the issues on disk 1, then the parity rebuild failed on parity 2 30% through, replaced that drive, now it's back to stuck at 100%. So I guess the next step is to replace the RAID controller. Any recommendations on Dell RAID controllers? The server is an R610 and my current RAID is the PERC H700 controller. Thank you!
August 3, 20232 yr Author I will have to look into the LSI HBA. Before your reply I went ahead and purchased another PERC H700 and battery. This resolved an issue I was seeing in that my storage battery was reporting low, but even after replacing the RAID controller and fixing all of the known issues my parity rebuild still gets stuck at 100%. I have two parity drives. I am rebooting now and setup a new config and see if it will pass by just using one parity disk, one of which is only 2 weeks old now. Attaching my current diag, but not sure what to look for in regards to the parity rebuild getting stuck at 100% even with a new raid controller. tower-diagnostics-20230803-0712.zip
August 6, 20232 yr Author @JorgeBOkay, I'm looking at the controllers you recommended now. I've tried just using one drive for parity and it still gets hung at 100%. Obviously with the R610 it's going through the RAID controller, but I'm setting up each drive as it's own virtual disk, so I'm not using the controllers RAID across multiple drives, each single drive is in it's own group (6 drives = 6 virtual drives), then just letting UNRAID handle everything. The odd part is that I have used this setup for 6+ years and even after replacing the controller with a known working controller it is still behaving the same. The parity drive I'm trying to u se now is also brand new.
August 6, 20232 yr Author @JorgeB Do you know if this card would be a good replacement for my Dell PowerEdge R610 server's PERC H700? I was trying to search the form for others doing the swap, but my search skills are failing me. https://www.amazon.com/BEYIMEI-Controller-Expansion-Non-Raid-Converter/dp/B08DFK4LZ7/ref=sr_1_3?keywords=ASM1166&sr=8-3&th=1 Thank you! It would be nice to not have to deal with the goofy raid/virtual setup situation for sure! Edited August 6, 20232 yr by vhariable
August 7, 20232 yr Community Expert It should work if the drives are connected using SATA cables, I would assume a server would use SAS type cables.
August 11, 20232 yr Author Thank you for all of the information as that new card did the trick! Finally have parity back!
