Sorry about pestering you guys, let me know if this is not the best list for
this type of question.
Anyway, an NFS storage issue ...
-------------------------
SAN/NAS BOX (NFS Server):
-------------------------
/ filesystem on VolGroup00/LogVol00 = 7.6GB
A 20GB filesystem on vg_vm/lv_vm1 is mounted at /srv/vm1
A 100GB filesystem on vg_vm/lv_data1 is mounted at /srv/data1
Output of 'df -h' (extraneous stuff removed):
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
7.6G 1.8G 5.5G 25% /
/dev/mapper/vg_vm-lv_vm1
20G 173M 19G 1% /srv/vm1
/dev/mapper/vg_vm-lv_data1
99G 188M 94G 1% /srv/data1
/srv/vm1 and /srv/data1 are mounted with 'mount --bind' to /exports/vm1 and
/exports/data1, then exported using NFS:
/exports 192.168.1.28(ro,fsid=0)
/exports/vm1 192.168.1.28(rw,no_root_squash,sync)
/exports/data1 192.168.1.28(rw,no_root_squash,sync)
---------------------
VM HOST (NFS client):
---------------------
On the NFS client, these shares are mounted to /vm/san as follows:
mount -t nfs4 192.168.1.49:/ /vm/san
[r...@vmhost ~]# ls -al /vm/san/
total 32
drwxrwxrwx 4 nfsnobody nfsnobody 4096 Sep 2 12:12 .
drwxr-xr-x 7 root root 4096 Sep 2 12:31 ..
drwxr-xr-x 2 nfsnobody nfsnobody 4096 Sep 2 12:59 data1
drwxr-xr-x 2 nfsnobody nfsnobody 4096 Sep 2 12:12 vm1
I can write to these directories so all seems good.
However, 'df -h' on the client side shows (extraneous stuff removed):
Filesystem Size Used Avail Use% Mounted on
192.168.1.49:/ 7.6G 1.8G 5.5G 25% /vm/san
In other words, the 20GB + 100GB LVs on the NFS server side are now showing up
as 7.6GB in size on the client size ... This is the size of the / filesystem on
the server side.
Virt-manager of course complains when I try to create a 15GB image file in
/vm/sam/vm1, it thinks the entire /vm/san filesystem has only 5.5 GB free.
What am I doing wrong here? I'm guessing my NFS setup is incorrect somehow?
Thanks yet again,
