I changed a drive in a Raid 6 array and while I'm watching the rebuild,
this is what I see from the atop command:
DSK | sdo | busy 99% | read 397/s | write 0/s | avio 2 ms |
DSK | sdm | busy 64% | read 0/s | write 310/s | avio 2 ms |
DSK | sdk | busy 62% | read 577/s | write 0/s | avio 1 ms |
DSK | sdp | busy 60% | read 579/s | write 0/s | avio 1 ms |
DSK | sdi | busy 60% | read 584/s | write 0/s | avio 1 ms |
DSK | sdn | busy 60% | read 578/s | write 0/s | avio 1 ms |
DSK | sdj | busy 59% | read 587/s | write 0/s | avio 1 ms |
DSK | sdl | busy 59% | read 580/s | write 0/s | avio 1 ms |
sdm is the new drive, all drives are identical and connected to the same
LSI controller. Is this normal or sdo is having problems?
