Debugging
Check loggings on target side in menu Jobs. Either click on „replicate“ under Joblog for an overview of the last
replication runs. A more detailled view is available when you click under „Last“ to the date entry that shows
loggings of the very last run.
You can also check loggings on source side in menu „Jobs > Remote“
The communication details are logged in menu „Jobs > Monitor“.
Clear the monitor prior a replication run to display only new events.
Sometimes it is helpful to start a replication as root from a console. You can start a job with the command:
perl /var/web-gui/data/napp-it/zfsos/_lib/scripts/job-replicate.pl run_12345
Replace 12345 with the job-id
Sometimes a pool is blocking/ remains busy for whatever reason
Try to export/ import the pool (zpool export -f poolname) . If this fails, reboot
Continue a replication if you reinstall an OS
If you reinstall the OS you must either restore group and job settings. The easiest way is when you have used
a napp-it backup job (Menu Jobs) that creates a backup of group and job settings on your first datapool under
backup_napp-it. In such a case you can restore the files under /var/web-gui/_logs/jobs and /groups manually.
With napp-it Pro and the ACL extension, you can easily restore all user, group and napp-it settings in menu
User > Restore Settings
If you do not have a backup of the job and group settings, first rebuild the group with menu
Extension > Appliance Group > ++ add. Then list the snaps and check for the jobid of the former replication job.
Then create a new replication job with the same source and target filesystem.
Enter the former job-id in the field „Force jobid“. You can then continue the replication job without the need
of a new initial transfer.
If you must do a new initial transfer, rename the old target filesystem for backup reasons. The start an
initial transfer. On success you can delete the old renamed filesystem.
Naming of napp-it replication snaps:
On the source system ex:
mail/data@1404222498_repli_zfs_backup1_nr_528 where
mail/data
is the source filesystem that is replicated
1404222498 is the jobid
backup1 is the hostname where it replicates to
528 is the ongoing number of the snap (to identify identical snaps on source and target)
On the target system ex:
backup/repli_mail/data@1404222498_repli_zfs_backup1_nr_528
backup/repli_mail/data is the target filesystem of the replication
1404222498
is the jobid
backup1 is the hostname where it replicates to (this host)
528 is the ongoing number of the snap (to identify identical snaps on source and target)
