Bug reported : http://bugs.contribs.org/show_bug.cgi?id=9130 (http://bugs.contribs.org/show_bug.cgi?id=9130)
In testing a migration from SME8.2 ( fully updated ) to SME9_64 :
I have configured and run a Backup to local removable disk media/usbBackup on the sme8.2 machine.
Backup is Enabled.
Backup is made on local removable disk media/usbBackup
Number of rotating backup sets is 1
Number of daily backups contained in each set is 7
Compression level (0-9) of backup is 6
Daily backup occurs at 22:00
Each daily backup session is cleanly timed out after 8 hours.
Full backup sessions (new backup set) are allowed everyday
The backup runs successfully, and i can perform a verification of the backup on the sme8.2 machine successfully.
I removed the disk and performed a fresh install of SMe9.0_64. The new machine was configured with the same domain,host,server-mode & ip settings.
I then enabled the backup to local removable media :
Backup is Enabled.
Backup is made on local removable disk media/usbBackup
Number of rotating backup sets is 1
Number of daily backups contained in each set is 7
Compression level (0-9) of backup is 6
Daily backup occurs at 22:00
Each daily backup session is cleanly timed out after 8 hours.
Full backup sessions (new backup set) are allowed everyday
On performing :
Verify workstation backup
-------------------------------------
This option will display the names of all files in a previously created workstation daily backup. You can use this option to verify the contents of the backup.You must choose the backup you want to verify
Only files flagged with [Saved] are contained in the backup.
Backup files are verified from shared folder : localhost/media/usbBackup/s9-1.sme
Select backup file: full-201511091801 (set1)
Error Message :
Verify workstation backup
The following files are considered in the backup :
Final memory cleanup...
Error while reading files from : /media/usbBackup/s9-1.sme/set1/full-201511091801
Nothing is logged in /var/log/messages.
I have also found the same issue when performing the same operations on a proxmox VM's, BUt using NFS shares.
Noted that after the error messages that if one checks for mounted filesystems that the usb drive is still mounted :
[root@s9-1 media]# mount
/dev/mapper/main-root on / type ext4 (rw,usrquota,grpquota)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/md0 on /boot type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/sdb1 on /media/usbBackup type ext3 (rw)
Changed subject line as this also causes Restore to fail

The differences between the SME8.2 dar and libdar versions compared to SME9.0 appears to be the cause of this issue, smeupdates-testing currently has new rpms waiting for release.
SME9.1RC1 has the latest versions so is not susceptible
So if you have a sme8.1 system don't update to sme8.2 prior to doing a upgrade to sme9.0 using the backup/Restore functions from the server-manager. Please NOTE this only affects the soon to be obsoleted SME9.0....
Upgrade to a SME9.1RC1 system is uneffected
Backups from the console are different and would appear from my limited testing to be unaffected

For those testing migration to sme9.0_64 and that have already updated to sme8.2 and still want to test now :
yum update --enablerepo=smeupdates-testing dar libdar
edit : updates have been pushed through
so u can now run :
yum update --enablerepo=smeupdates-testing dar libdar You can then perform the restore and test further.
eish, wa winna wenna :D
edit : original subject shortened from : Re: Restore & Verification of workstation backup fails to read backup made on sme8.2
