XenServer 7.6: root partition is out of space

Indresh Yadav


Hi everyone,

We have upgraded the XenServer from 6.5 to 7.6. The upgrade went smoothly. It is a standalone node. I checked the the /dev/sda1 partition and it shows 3.4G. It is almost full now. I've checked all logs and cleared everything I could but no change. 

[root@loc ~]# df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        2.9G   60K  2.9G   1% /dev
tmpfs           2.9G  508K  2.9G   1% /dev/shm
tmpfs           2.9G  2.0M  2.9G   1% /run
tmpfs           2.9G     0  2.9G   0% /sys/fs/cgroup
/dev/sda1       3.4G  2.9G  357M  90% /
xenstore        2.9G     0  2.9G   0% /var/lib/xenstored
/dev/loop0       69M   69M     0 100% /var/xen/xc-install
tmpfs           593M     0  593M   0% /run/user/0

I know that the  partition can be increased to 18G in XenServer 7.6. Is there anyway we increase the partition space? Appreciate any input.


Thanks a lot!


Kind regards,

On a single host it would be best to export the VM's, install fresh and import the VM's.

I don't know of a way to reconfigure the partitioning any other way. Now you can touch

/var/preserve/safe2upgrade before an upgrade with no VDI's on the SR and the new 

layout will be installed.

Alas, my article on upgrading to a new partitioned version got deleted from the xenserver.org site when it was restructured.

Doing an upgrade and a new partitioning didn't work out well for me, hence I agree that exporting the VMs or migrating them to other pools might be the best bet, since a clean install is the safest way to get the new partitioning mechanism in place.
