Description Igor Krivenko 2009-08-20 06:02:33 UTC

For a md-device (say, /dev/md0) HAL tries to read information about rebuild process from sysfs file /sys/devices/virtual/block/md0/md/sync_action (refresh_md_state() function from hald/linux/blockdev.c). 
This operation is skipped for linear RAID devices because they provide no redundancy and thus don't support rebuilding (there is no /sys/devices/virtual/block/md0/md/sync_action file).

According to the same logic and the kernel documentation HAL should skip this step also for RAID0 devices. Now refresh_md_state() just fails for such a device and eventually HAL ignores it.
