fsck on machines

Hey during the ovirt live nightly run the log shows /sbin/resize2fs: Attempt to write block from filesystem resulted in short write while trying to resize /var/tmp/imgcreate-ieeDaG/tmp-dYjzeM/ext3fs.img Please run 'e2fsck -fy /var/tmp/imgcreate-ieeDaG/tmp-dYjzeM/ext3fs.img' to fix the filesystem recommending to run e2fsck. do you think it's some disk corruption on the slave? previous run of this job worked.
