Subject: Re: raid1 issue after disk failure: both disks of the array are still active
Date: Fri, 14 Sep 2012 09:45:26 +0200 [thread overview]
Message-ID: <5052E096.5040509@linuxsystems.it> (raw)
In-Reply-To: <alpine.DEB.2.00.1209140912350.13902@uplift.swm.pp.se>
I also would like to know if the raid1 will *surely* use data from the
other disk to write on the broken sector after a CHECK. I mean, i did
nothing even after a read error on md0 with a "failed command: READ DMA"
in dmesg (possibly because after a few reads it succeeded reading?). I
read that when raid1 is in doubt there is a 50%-50% chance it uses data
from the good disk, wouldn't be better to fail the broken disk and then
re-add it to the array?
Cheers,
Niccolò
