I have a server which is running customized version of Debian. It is attached a sun storage raid. It has very limited tools and installing new tools is not allowed. :(
This message I see in
end_request: critical target error, dev sda, sector 556782970 sd 0:0:0:0: [sda] Unhandled sense code sd 0:0:0:0: [sda] Result: hostbyte=0x10 driverbyte=0x08 sd 0:0:0:0: [sda] Sense Key : 0x4 [current] sd 0:0:0:0: [sda] ASC=0x44 ASCQ=0x0 sd 0:0:0:0: [sda] CDB: cdb=0x28: 28 00 21 2f d5 7a 00 00 08 00 end_request: critical target error, dev sda, sector 556782970
So it seems there is badblock in sector 556782970, but I don't know which hard drive it belongs to so that I can get it replaced.
arcconf getlogscommand does not reveal any issues with drives.
arcconf task start 1 logicaldrive 0 verify_fixbut this didn't help.
I did an
e2fsckcheck. It attempts to fix some inodes but above issue remained. (I assume since its physical issue).
