Backup to Mounted Folder Fails
avi120
✭
We have a three node setup with ips 172.18.255.21, 172.18.255.22, and 172.18.255.23. Each of the nodes has a mountpoint to an external storage.
mount.cifs //172.18.255.80/share_vertica/ /mnt/share -o username=admin
When I use the following configuration from node1 (172.18.255.21) all works well.
1)
[Mapping]
v_pm_node0001 = 172.18.255.21:/mnt/share/backup_pm1/
v_pm_node0002 = 172.18.255.21:/mnt/share/backup_pm1/
v_pm_node0003 = 172.18.255.21:/mnt/share/backup_pm1/
However when I do the following if tails
2)
[Mapping]
v_pm_node0001 = 172.18.255.21:/mnt/share/backup_pm1/
v_pm_node0002 = 172.18.255.22:/mnt/share/backup_pm1/
v_pm_node0003 = 172.18.255.23:/mnt/share/backup_pm1/
It fails with the following error
[vertica@dal_server1 FROM LSN SETUP]$ /opt/vertica/bin/vbr.py -t backup -c backup_pm.ini
Error: Unable to lock backup location: [Errno 13] Permission denied. Hint: You must have permission to backup locations and the filesystems must support POSIX file locking.
Backup FAILED.
If I do the following that does not use the mounted directory, but only the local disk it works as well even with the IP Mapping that did not work in case #2.

v_pm_node0001 = 172.18.255.21:/tmp/backup_pm1/
v_pm_node0002 = 172.18.255.22:/tmp/backup_pm1/
v_pm_node0003 = 172.18.255.23:/tmp/backup_pm1/
The following are the vbr log files from the 3 nodes
