I have an HP Z800/dual Xeon/81GB server running 6.12.14.

 

A couple of months ago I installed an LSI 9211 SAS HBA card, which has been working flawlessly.

4 Days ago, I acquired 3 x HGST 12TB SAS drives and installed them into the array (cf Xeus Array.png). 2 were installed as new parity drives, and the other as Disk 8. I rebuilt parity first, then installed Disk 8 after pre-clearing. All was fine at this point.

I then moved all files from the 4TB disks in turn with Unbalance starting with Disk 7, the 6, 3 & 4 in turn respectively. All went fine until the final transfer of files from Disk 4 last night. 

Midway through the process, I noted that Parity 2 & Disk 8 were disabled and that Disk 8 was being emulated. As there were only 3 or so hours to run til completion I let Unbalanced finish doing its thing. I do not know in which order the drives were disabled.

 

I then generated the diagnostics, SMART reports & screenshots attached which you will note include a File System check of Disk 8

I haven't done anything else since. (I just downloaded and attached SYS+logs as I type this)

 

I'm not sure what to do from here to resolve the issues. I'm hoping both SAS drives aren't toasted as I do not have spares to replace them at hand.

Any guidance on how to troubleshoot this would be greatly appreciated.

If you need any more info please ask.

 

Thanks In advance,

GeeTeeNZ

Looks more like a power/connection issue, check/replace cables and post new diags after array start.

Due to Drive Bay constraints I had to jury-rig the drive connections (ie they are not in Bays currently) till I can remove the 4TBs from the array.

I have "rejigged" things slightly, checked the connections, and restarted. Diags attached.

No disk errors for now and emulated disk8 is mounting, assuming contents look correct, you can rebuild on top (and re-sync parity2 at the same time), any errors during the rebuild grab new diags.

Thanks Jorge. Have actually had to remove Parity2 to ensure things worked better. Have started rebuilding Disk8. 

I'm going to have to do another parity rebuild when I remove the 4 4TB drives, so I'm assuming I can reintroduce the 2nd parity drive then.

 

cheers for the help mate.
