I have a RAID 5 array of 4 disks. In the last 2 days I began to see these messages in the log:
Jun 13 23:01:05 localhost smartd: Device: /dev/sda [SAT], 1 Currently unreadable (pending) sectors Jun 13 23:01:05 localhost smartd: Device: /dev/sdb [SAT], 2 Currently unreadable (pending) sectors
If I have 2 faulty disks then the array should not show all disks OK:
md0 : active raid1 sdd1 sdb1 sdc1 sda1 64128 blocks [4/4] [UUUU]
Strangely there are no other problems just the log messages. I am worried because sda is new and I previously had problems with sdb. (Completely died but the guy who sold it to me fixed it somehow.) Am I in danger of losing data? What should I do now?
