Subject: RAID 1 not fixing up sector errors?
Date: Thu, 14 Apr 2016 16:03:59 +0300 [thread overview]
Message-ID: <29813347.d6oRyCVBGp@dag.newtech.fi> (raw)
Hi!
Have set up a RAID1 here for temporary storage of some backup files.
As I am using Seagate barracudas I am prepared for sector errors :-).
that's why I am using RAID1.
Anyway I do get those occasional "Pending Reallocate" with
the appropriate corresponding
Unrecovered read error - auto reallocate failed
in the log.
A resync of the array will rewrite the failing sector
and the drive seems to reallocate it and all is fine again .
But I was expecting the MD layer to try to fixup that sector
automatically by using the data from the other drive ??
Is there something I need to explicitly enable?
Or am I expecting too much ;-)
Best
Dag
