Latest XCP-ng 8.2: Cannot import XVA, even with latest XOA

[bsodmike]

@olivierlambert Yes, a task is created (in XOA), which never ends.

With xe vm-import it creates a VM in yellow state, but never progresses beyond that.

I just setup a fresh install of Ubuntu 20, I'll export it and try and re-import it as XVA.

[olivierlambert]

Is the task having any progress?

[bsodmike]

@olivierlambert Hang on there's a sliver of progress now!

[bsodmike]

@olivierlambert It's showing 1% but not doing much beyond that.

[olivierlambert]

Anything happening in xensource or SMlog?

[bsodmike]

@olivierlambert Nothing out of the ordinary. Still 1%.

[olivierlambert]

Then you have an issue on the storage or in the XVA file itself.

[bsodmike]

@olivierlambert it's definitely not the storage, will try a different XVA to isolate.

[bsodmike]

@olivierlambert Are there any compatibility issues, i.e. say exporting a XVA with an older version of XCPng and trying to import with a newer version?

[olivierlambert]

No known issue with XVA import. Nor any recent tickets about this kind of problem.

@olivierlambert Thanks your comments got me thinking, it could be the NFS mount connection is dropping out; trying a test now to mount it via fstab in XCPng.

[bsodmike]

@olivierlambert here's another clue. If I mount my local CIFS share onto the XCPng host, after a while I cannot do

cd /mnt
ls -la
# it just hangs here.  I have to kill the SSH session and SSH back in

This only happens after mounting the CIFS share the very first time after boot.

Thoughts?

@olivierlambert bit more info

[20:42 xcpng-host0 ~]# mount -t cifs
//10.0.x.x/linux_data on /mnt/linux_data type cifs (rw,relatime,vers=3.0,cache=strict,username=myuser,uid=0,forceuid,gid=0,noforcegid,addr=10.0.x.x,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,noperm,rsize=1048576,wsize=1048576,echo_interval=60,actimeo=1)
[20:42 xcpng-host0 ~]# cd /mnt/linux_data
# it just hangs here.  I have to kill the SSH session and SSH back in

[olivierlambert]

That's your problem: fix your storage (reboot your host to see), and then import will work

[bsodmike]

@olivierlambert Hah, indeed it was! CIFS is totally unstable, but I was able to get NFS working with these configs:

mount -o vers=3,soft,mountproto=tcp [IP]:/share /mnt/nfs_share/backup.xva
