Dear All,

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

Code:

Info fld=0x7251240
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

Info fld=0x731faba
end_request: I/O error, dev sda, sector 120715962
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?

Code:

lvdisplay -m /dev/vg0/lv4

Use the pvmove command to empty the unwanted PV and then pvremove to, er, remove it.
