Red Hat Bugzilla – Bug 118956
RAID won't be started if filesystem table uses disk label
Last modified: 2014-03-16 22:43:29 EDT
Description of problem:
Its possible to refer to RAID disks in fstab using their filesystem
label. OK, there's not much benefit to doing this, but many customers
simply seem to prefer using disk labels for everything (I teach RHCEs
and notice this). Since rc.sysinit only looks for the raid device in
/etc/fstab, RAID won't be started if the fstab is using a label to
refer to the FS on the RAID disk.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Create a RAID device. Make a labelled filesystem on it.
2.Add it to the fstab using its disk label
RAID won't be started. Not too bad, but then fstab will be run, and
may tell the user the user the filesystem is larger than the device -
a fairly confusing error message.
Either deal with RAID filesystems using disk labels or produce a
better error message.
This problem is resolved in the next release of Red Hat Enterprise Linux (RHEL
4), with the added support for using mdadm to start arrays. Red Hat does not
currently plan to provide a resolution for this in a Red Hat Enterprise Linux
update for currently deployed systems.
With the goal of minimizing risk of change for deployed systems, and in
response to customer and partner requirements, Red Hat takes a conservative
approach when evaluating changes for inclusion in maintenance updates for
currently deployed products. The primary objectives of update releases are to
enable new hardware platform support and to resolve critical defects.
