Add datastore connection timeout

[Roy Compass]

Hi,

I was getting Connection error - Timeout when adding datastore on the web interface. The datastore was actually created after about 15 minutes, despite the error.


The datastore is created on this NFS share.

192.168.226.89:/mnt/RAIDA/backup/backup on /mnt/datastore/backup-pbs-nas type nfs (rw,relatime,vers=3,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.226.89,mountvers=3,mountport=995,mountproto=udp,local_lock=none,addr=192.168.226.89,_netdev)

It looked like after the connection timeout message, the process was still creating sub-folders in .chunks. Once .chunks had 65536 or 65537 folders, the datastore was created successfully.


Running proxmox-back-manager in cli returned no error.

proxmox-backup-manager datastore create backup-pbs-nas /mnt/datastore/backup-pbs-nas

Hi,

This is a known issue with NFS backed (or generally slow) storage. As you noticed yourself, the job actually does continue in the background, it just doesn't return before the HTTP request timeout. You should still see status updates by monitoring the system log. Otherwise, as you noticed, using the cli avoivds the issue entirely. Upon completion, the datastore should work as expected.
