The nature of the errors suggest to me a race condition or off by one bug. In all but one case the problem is the count being off by one. In the one exception the count is off by two. I didn't receive complaints from fsck on previous reboots after the creation of the filesystem. The shutdown before the startup that resulted in these errors seemed to have gone normally. I do remember rsync complaining about at least mpc1211 during the rsync that copied the data across the network from another system. I don't remember the complaint. Most of the files on the filesystem are video files in the 100mb+ range. There are also other large files like isos, virtualization images, etc. All the files complained about are really small files. The underlying layers are Linux software raid5 running on 6 1tb hard drives. Other arrays using the same drives are raid1 and raid10. mkfs command used to make the filesystem: mkfs.ext4 -j -b 4096 -i 524288 -m 0 -E stride=256 -O extents /dev/md3 Other messages that may relate: EXT4-fs: barriers enabled EXT4-fs: barriers enabled EXT4-fs: barriers enabled JBD: barrier-based sync failed on md1:8 - disabling barriers JBD: barrier-based sync failed on md2:8 - disabling barriers JBD: barrier-based sync failed on md3:8 - disabling barriers df -h output: /dev/md1 32G 5.3G 25G 18% / /dev/md0 198M 14M 174M 8% /boot /dev/md2 288G 60G 229G 21% /home /dev/md3 4.1T 2.3T 1.8T 56% /home/data An automatic fsck check on boot started, and saw errors.
