Hello,

I've got bacula on debian from backports -> version 2.4.4. As storage
i use HDD - raid 1 (no tape).

Backups are done without error. But than when i want to restore
something,...sometimes it fails because of bad checksum..its not just
that one volume..actually most restore jobs fails.

e.g.:
08-Nov 12:41 host-sd JobId 268: Ready to read from volume
"Volumes0067" on device "FileStorage" (/backups/).
08-Nov 12:41 host-sd JobId 268: Forward spacing Volume "Volumes0067"
to file:block 0:198.
08-Nov 12:41 host-sd JobId 268: Error: block.c:318 Volume data error
at 0:626540712!
Block checksum mismatch in block=9713 len=64512: calc=12e65067 blk=5d0e32ee

Disks are apparently ok - SMART and badblocks didnt find anything.

Ive tried to extract that volume with bextract and of course result is
same (since its using same code i guess:)
27-lis 02:17 bextract JobId 0: Error: block.c:318 Volume data error at
0:324689092!
Block checksum mismatch in block=5034 len=64512: calc=e7cf8c6b blk=c0d129b3
27-lis 02:17 bextract JobId 0: Error: attribs.c:421 File size of
restored file tmp//var/spool/cyrus/mail/c/user/cxxxx/Sent/155. not
correct. Original 2515248, restored 1245184.
bextract: acquire.c:436-0 dir_update_vol_info. label=64 Vol=Volumes0067


Please do you have any suggestion where could be problem?
Thanks

Radim
