Hope someone can give me advice,

Had an error warning stating:

Tower kernel: blk_update_request: I/O error, dev sdg, sector 732971568 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0

and array shows 1 error against sdg. This was after a successful parity check stating the array health was a pass.

SMART page states an error but nothing is obvious (to me) in the extended SMART report. 

 

HP Proliant Microserver Gen 8

1 SATA parity drive

3 SAS drives via HBA

1 SATA Cache

Error was after spin up, some combinations of drives/controller can cause this, you should update the LSI firmware to latest, it might help, if it doesn't you can try reporting the issue in the SAS spin sown plugin support thread, or disable spin down for that drive.

 

 

 

I had trouble with the HP 220 branded Broadcom / LSI 2308 card after I updated to V20 as I then had problems with SSD trim operations which turns out V20 doesn't support so I had to downgrade to p16.

Just happened again when I came out of maintenance mode:

All three SAS drives are identical so odd that only sdg is flagging?
