Summary: Filesystem corruption with large filesystem on FC3
Product: Linux XFS
Version: Current
Platform: IA32
OS/Version: Linux
Status: NEW
Severity: critical
Priority: High
Component: XFS kernel code
AssignedTo: xfs-master@xxxxxxxxxxx
ReportedBy: davidc@xxxxxxxxxxxxx
Hardware: Tyan S2665 motherboard, 4GB RAM, 2x Xeon CPU, IDE drive /dev/hda as
system disk. 3Ware 9000 RAID controller running 12 Maxtor 250GB SATA disks
(2.8TB).
FC2 installed and parted used to create one large volume on /dev/sda1. mkfs.xfs
used to create XFS filesystem:
mkfs.xfs -i size=512 -f /dev/sda1
Volume mounted and large quantity of test data copied onto it. All seemed OK
until the FC3 update, when the FC3 installer complained that /dev/sda1 was not
formatted.
Removed /dev/sda1 from fstab and installed FC3 as update
Tried to mount existing volume /dev/sda1 - mount gives message:
mount: /dev/sda1: can't read superblock
Ran xfs_check. Received the following messages:
XFS: totally zeroed log
can't seek in filesystem at bb 2870001664
can't read btree block 17/2092163
extent count for ino 46904 data fork too low (0) for file format
bad nblocks 5247 for inode 46904, counted 0
bad nextents 33 for inode 46904, counted 0
/usr/sbin/xfs_check: line 56: 3132 Segmentation fault xfs_db$DBOPTS -i
-p xfs_check -c "check$OPTS" $1
Repeated parted and mkfs.xfs step to recreate partition and filesystem (comes
out as 2.4 TB or so). Repeated copy of about 500GB data to filesystem.
Unmounted volume. Remounted volume - okay. Rebooted. Volume will not now
remount and I get the same messages from xfs_check.
