Re: [Bacula-users] Bacula Restore keeps crashing with Block checksum mismatch
Hello,
my problem seems to be solved. It seems to have something to do with the block
size. I set both the minimum and the maximum blocksize of the device to 64KB
and the restore works:
Device {
Name = TestStorage
Media Type = File
Archive Device = /mnt/notfallserver/vollbackup
LabelMedia = yes;
Random Access = Yes;
AutomaticMount = no;
RemovableMedia = no;
AlwaysOpen = yes;
RequiresMount = no;
Minimum Block Size = 65536
Maximum Block Size = 65536
}
It works with 16KB fixed block size, too. Beforehand I did not set the block
size.
Greetings,
Sven Hendriks

Hello,
I'm running Bacula 2.0.2 built from source on the following system:
XEN 3.0 with Gentoo, Kernel 2.6.16 as Dom0 running bacula-dir and
bacula-sd. One deamon bacula-fd is also running here for test restores.
File system is Ext3. Debian, Kernel 2.6.16 as DomU running one file daemon
for backup. The file system here is XFS. The backups are done from the
DomU
file daemon and are stored via the storage daemon on a samba share with
NTFS mounted with the cifs option in the Dom0.
Backups are running well, unfortunately the Restores do not. Everytime I
try to restore a backup sooner or later I get an error message like
Error: block.c:317 Volume data error at 0:2068512761!
Block checksum mismatch in block=65353 len=64512: calc=3deeeba7
blk=962bd82e
and later
Error: attribs.c:409 File size of restored file X not correct.
Original Y, restored Z.
and Bacula stops.
I tried to restore from the samba share to the same samba share into
another directory via the file daemon on Dom0 and from the samba share to
a
XEN DomU with XFS via the file daemon on DomU. In both cases I get the
error messages above. The backups are running at night, so it is very
unlikely that file sizes are changing during backup. I hope my
descriptions
are not too confusing :-) I have no idea what causes this error and I'd be
grateful for any hint that may help to solve my little problem.
Greetings,
Sven Hendriks

Hello Kern, thank you very much for this hint, but the volume size is already limited to 2GB.

Far better to put a samba-fd directly on the host machines. Samba can be built without large file support, if the OS that it is built on does not support it or similar reasons. There can be a 2GB limit either within Samba or within the OS of the machine running Samba. HP-UX, for example, has to have its filesystems formatted the right way and to have Samba built the right way. - -- _ _ _ _ ___ _ _ _ |Y#| | | |\/| | \ |\ | | |Ryan Novosielski - Systems Programmer III |$| |__| | | |__/ | \| _| |[EMAIL PROTECTED] - 973/972.0922 (2-0922) \__/ Univ. of Med. and Dent.|IST/AST - NJMS Medical Science Bldg - C630 -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFF5KIZmb+gadEcsb4RAqvRAJ4lX4L4O5Y3nX/NgdCsqaJys0jq2wCgi5uU V3Addeir2mEtZtGLVTScP8A= =l7wj -END PGP SIGNATURE- - Take Surveys.
