I received a kernel Oops while un-tarring a backed up root file system
to a btrfs partition.
I''m running the btrfs-unstable.git version as of commit 035fe03a Thu,
28 Jan 2010 21:20:39 (Btrfs: check total number of devices when
removing missing) back-ported to a 2.6.32 kernel.
I was attempting to restore a backed up root partition to a freshly
formatted btrfs volume. This partition was formatted with the
defaults. The target btrfs files system was a relatively small 9.4GB
partition on a 250 GB WDC WD2500JB-55R EIDE drive.
I had intended to mount the partition compressed, but accidentally
mounted the partition without compression and over-filled the
partition. Still, I was expecting the operation to fail without an
Oops.
I could see that the tar command was continuing to attempt to extract
files even after the volume had filled up. I''ve seen a few patches
regarding changes in the error return code, and was wondering if one
of these patches was relevant.
I am attaching the dmesg output for two Oops events. The first one
occurred during the tar extract operation which filled the disk. The
second Oops occurred when trying to unmount the btrfs volume after the
first Oops.
