Hi guys.
My RAID array just kicked out one of the drives again at heavy activity
running:
# ddrescue -n -f /dev/fridge/storage storage.img ddrescue.log
where the /dev/fridge/storage LV Size is 4.88 TiB
What's strange is the device is there:
brw-rw---- 1 root disk 8, 144 Oct 2 11:48 /dev/sdj
But the /dev/sdj1 which should hold Linux raid autodetect partition just
disappeared...
# fdisk -l /dev/sdj
Disk /dev/sdj: 2000.4 GB, 2000398934016 bytes
255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdj1 63 3907029167 1953514552+ fd Linux raid
autodetect
Is this a normal behavior? I don't understand either why the heck is the
RAID degrading all the time ?
I replaced all the cables with SATA3 cables, the BIOS is updated, both
the motherboard and the drives are SATA3 and brand new.
I could not find anything about the RAID being degraded or the device
having problems in dmesg, /var/log/messages, /var/log/syslog or
/var/log/kern.log
I'm on Debian Wheezy
