Checking Filesystem: Could not open -a

Question

Hi,
I just noticed a problem during the filesystem check at boot time, a message like the following floats by (are the initscript messages logged somewhere?):
::Checking Filesystems
Could not open -a
/dev/sda2: clean ....
Could not open -a
Then the boot continues. I tracked it down to the fsck in /etc/rc.sysinit, line 263.
The scenery is:
kernel26 2.6.34-2
initscripts 2010.06-2
/dev/sda2 is my /boot partition
my root partition is on /dev/sda4 and is a btrfs one
/home is a subvol of the btrfs partition but of course has its own entry in /etc/fstab
I do have another partition using LVM, but that is currently not used (and not in fstab)
Has anybody else seen this?
Could the btrfs stuff be a problem?

Answer 1

I recently went back to ext3 (dropping all btrfs partitions) for various reasons, which also solved this problem.
