Package: hdparm
Version: 8.9-1
I'm running a system with several soft RAID1 & RAID6 devices. I
experienced a problem where the resync/rebuild of my new array's stalled
at 0K/s speed like this:
md3 : active raid1 sdb6[2](F) sda6[0]
126953536 blocks [2/1] [U_]
[>....................] recovery = 0.0% (103296/126953536)
finish=634251.2min speed=0K/sec
md4 : active raid6 sdf1[3] sde1[2] sdd1[1] sdc1[0]
976767872 blocks level 6, 64k chunk, algorithm 2 [4/4] [UUUU]
[>....................] resync = 0.2% (1037056/488383936)
finish=289250.7min speed=0K/sec
Now it turns out that his is caused by /etc/default/hdparm's
"RAID_WORKAROUND" (if it's enabled/set to 1). The min/max construction
speeds get set to 0 (by the hdparm init script) at boot but are never
restored to their original value's OR the kernel doesn't like this
behaviour, I don't know (yet).
