Trouble mounting NFS share

mbraun · Apr 26, 2012

Hi all,

congratulations to the release of Proxmox 2.0, it really solves a lot of issues with the 1.x generation and brings a load of new features!
While setting up a evaluation machine, i ran into some trouble with NFS shares. Adding a share and selecting the export works fine, even size and usage information are shown correctly. However, when i select the "Content" tab, the system raises an "Internal Server Error (500)". Find syslog with NFS debugging output attached.

System is a 2xE5620, 48GB Mem, Debian Squeeze

Greetings
Martin

check permisson on the nfs server, give details.

second, make sure that you run the latest version of 2.x, post 'pveversion -v'

Tom,

thanks for the hint! The issue was that the nfs module seem to require a subfolder structure /template/iso at the NFS server. However, the / directory of this NFS server is not writeable so the connection fails. I'm not sure if this may be considered as a bug, templates should be optional?

Thanks a lot!
Martin

yes, the NFS share needs to be writable.

afaik there is already a feature request for read-only nfs shares.
