Dear All,

I have issue with one of my server HDD. (/dev/sd)

Code:

end_request: I/O error, dev sda, sector 119870016

sd 0:0:0:0: SCSI error: return code = 0x08000002

sda: Current: sense key: Medium Error

Add. Sense: Read retries exhausted

sd 0:0:0:0: SCSI error: return code = 0x08000002

sda: Current: sense key: Medium Error

 Add. Sense: Read retries exhausted

how can I remove /dev/sda7 from /dev/vg0/lv4?
