Subject: [3.2.2] tasks blocked during matrix auto checking.
Hi,
on heavy loaded opterons i've noticed some blocked tasks during matrix auto checking.
is it a known issue?
(...)
[401836.109354] md: data-check of RAID array md0
[401836.109364] md: minimum _guaranteed_ speed: 1000 KB/sec/disk.
[401836.109368] md: using maximum available idle IO bandwidth (but not more than 200000 KB/sec) for data-check.
[401836.109388] md: using 128k window, over a total of 8000256k.
[401836.111441] md: delaying data-check of md2 until md0 has finished (they share one or more physical units)
[401914.274728] md: md0: data-check done.
