Bug 395883 – app-arch/dump-0.4.44-r1: stabilize (current stable creates garbage with ext4 with stable e2fsprogs-libs-1.41.14)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Konstantin Bryzgalov 2011-12-24 11:02:50 UTC]

Restored data from dump.file created with dump is GARBAGE.
dump 0.4b41 (using libext2fs 1.41.14 of 22-Dec-2010)



Reproducible: Always

Steps to Reproduce:
1. 
# dump -0af /root/xen/obraz-x64-gentoo-begin.dump /dev/md4 
# echo $?
0

On /dev/md4 installed gentoo, ext4 on mdraid, raid1.
And /dev/md4 not mounted

2. 
# dd if=/dev/zero bs=1M count=6144 > gentoo-x64-iscsi.dd
# losetup -a
# losetup /dev/loop0 gentoo-x64-iscsi.dd
# mkfs.ext4 /dev/loop0
# mount /dev/loop0 /mnt/gentoo/
# cd /mnt/gentoo/

1 variant:
# restore -xf /root/xen/obraz-x64-gentoo-begin.dump
restore: ./lost+found: File exists
You have not read any volumes yet.
Unless you know which volume your file(s) are on you should start
with the last volume and work towards the first.
Specify next volume # (none if no more volumes): none
You have not read any volumes yet.
Unless you know which volume your file(s) are on you should start
with the last volume and work towards the first.
Specify next volume # (none if no more volumes): none
Volume numbers are positive numerics
You have not read any volumes yet.
Unless you know which volume your file(s) are on you should start
with the last volume and work towards the first.
Specify next volume # (none if no more volumes): ^Crestore interrupted, continue? [yn] n

Result: Restored FS is corrupted. 

2 variant:
# mkfs.ext4 /dev/loop0
# mount /dev/loop0 /mnt/gentoo/
# cd /mnt/gentoo/
# cat /root/xen/obraz-x64-gentoo-begin.dump|restore -xf -
restore: ./lost+found: File exists
set owner/mode for '.'? [yn] set owner/mode for '.'? [yn] y
# echo $?
0
# cat -v etc/gentoo-release
M-^X^]eM-8M-`YM-KM-tM-^VM-^SM-^Q^NM-Si:M-WjSs^UM-eo^XM-+M-/;M-OM-[M-vM-q^OM-)@
                            
 OR

# chroot /mnt/gentoo /bin/bash
chroot: failed to run command `/bin/bash': Exec format error

Actual Results:  
app-arch/dump-0.4.41 create garbaged dump

Expected Results:  
app-arch/dump-0.4.41 create correct dump (may be restored)

[Comment 1 Konstantin Bryzgalov 2011-12-26 06:06:24 UTC]

dump 0.4b44 worked fine, then  dump-0.4.41 is desirable
away from the the default installation
