DELL Equallogic 6110. The RAID set lost blocks.
Hello all,
We`ve out of support 4 Dell Equallogic arrays (2x4110, 2x6110). We have of course problems with C2F modules on 6110, but this is not a problem that I face right now.
We`ve have on group with all arrays, Pool1 with volumes is on one PS4110 and PS6110, next PS4110 and PS6110 is Pool2.
I`ve set SyncRep between Pools on one test volume, but I`ve made restart of one controller on a arrays which is receiving SyncRep Volume. It cause diffrent then usual restart of array, after one minute CLI it says that array is not configured. I was wating on status change about 5 min but with no change was visible in CLI, then I decided to restart again opne of the controller, Array back to life but I receive that I`ve RAID set lost blocks.
There is no volume on that array in group because I`ve stop canceled SyncRep between pools.
I`ve no clue how to repair "RAID set lost block" issue without any volume on it?
Anyone? :)
There is no data lost in this case. This was test Syncrep prepared nad as I see this was good decision :)
Thanks in advance in any answer.

Hello Mark,
You can open a one time support call for a fee. They can help you with the lost blocks issue.
re: Volume space. Did you delete a volume recently? If so, check the recycle-bin in the EQL GUI. It's likely there.
Regards,
Don

Hello Mark,
Without more diagnostic information I can't answer that question. It depends on if the lost blocks are solely restricted to that volume or not.

Hello,
You are very welcome. Glad I could help.
It's not that they are independent of each other. It depends on if the block is associated with a volume, free space, replica, snapshot,or part of the internal elements of the array. If the block was unallocated then a RAID level command would be required to resolve it.

Hello Don,
After purging recycle bin with deleted volumes, the error subsided, I understand that the RAID structure on the array is independent of errors on volumes.
Thank you very much Don for help, sometimes small tips makes big things :)
