Bug#759063: mdadm RAID5 array intermittently stalls during a write operation

Package: mdadm
Version: 3.3-2
Severity: normal
Tags: upstream
I have a RAID5 array using 4x 3TB WD Red drives. On occasion while writing to
the array, the write operation will stall. Using iostat, I can see that one
of the member disks shows >95% utilisation performing reads at approximately
0.5MB/s. This stall usually takes about 10 seconds to recover, sometimes up to
a minute. Lengthy stalls cause Samba network transfers to fail, shorter stalls
are mostly harmless if not annoying. The SMART output for the offending member
drive looks clean. I did notice that I can reliably reproduce the stall by
restarting the array - the first write operation appears to trigger it. I've
had the array running for over a year and I've only just started noticing this
recently. All drives are using native SATA ports on the Asrock A75M-HVS
motherboard.
