Subject: data corruption after rebuild
Date: Tue, 19 Jul 2011 15:55:35 +0200 [thread overview]
Message-ID: <2073005.NH8LALaxuD@bloomfield> (raw)
Hi,
I have a big problem with mdadm, I removed a drive from my raid6, after
replacing it the raid started an online resync. I accidentally pushed the
computer and it shut down (power cord moved), and after booting it again the
online resync continued.
the problem is that the rebuilt array is corrupted. most of the data is fine,
but every several MB there is an error (which doesn't look like being caused
by a crash), effectively invalidating all data on the drive (about 7TB, mainly
HD video)
I do monthly scans, so the redundancy syndromes should have been up-to-date,
the array is made of 8 disks, the setup is ext4 on lvm on mdraid
is there anything to solve this? or at least ideas what happened?
