NFS problem

infraestrutura

When I mount an nfs volume on linux the capacity is recognized normally:

192.168.50.8:/vx/VMS_XCP2  103T  251G  103T   1% /run/xo-server/mounts/f2bb1ed9-f757-49cb-8e1c-42ad993d8b2a

In xoa the displayed capacity is different:

NFS_LOCAL	/run/xo-server/mounts/f2bb1ed9-f757-49cb-8e1c-42ad993d8b2a	
312.5 GiB / 9.87 TiB	163.81 MiB/s / 598 MiB/s	None

olivierlambert

Could it be an overflow when we parse the mount info? Any idea @julien-f ?

edit: @infraestrutura are you on XOA or XO from the sources? Is it fully up to date?

julien-f

@olivierlambert Yep, it's a known issue: https://github.com/vatesfr/xen-orchestra/issues/5637

As it's pretty rare, not a big deal and hard to fix, it's still here.

olivierlambert created this issue in vatesfr/xen-orchestra

closed Remote size incorrectly reported by xo-server #5637

@julien-f
But this problem is just visualization or does it interfere with the backup?

julien-f

@infraestrutura Just display, it does not impact anything else.
