RHBA-2010:0006 - mdadm bug fix update
Synopsis
mdadm bug fix update
Type/Severity
Bug Fix Advisory (none)
Topic
An updated mdadm package that fixes a bug is now available.
Description
mdadm is used to create, manage, and monitor Linux MD (software RAID) devices. It provides similar functionality to the raidtools package.
This updated package fixes the following bug:
- the previous mdadm update added a data scrubbing cron job, /etc/cron.weekly/99-raid-check, that looks for bad sectors on drives in redundant arrays and fixes the bad sectors using data from other drives to reconstruct sectors that return read errors. The script only performs checks on idle, healthy arrays but, previously, it initiated each check operation in turn, and switched idle arrays to active as it went. Consequently, if different arrays shared the same physical drive, the raid-check script only checked one of the arrays on that drive. With this update the raid-check script now gets the the state from all arrays on all drives before initiating the first check operation. Multiple arrays on a single device are now checked by the raid-check script as expected. (BZ#523000)
All mdadm users are advised to upgrade to this updated package, which resolves these issues and adds this feature.
