Hello Chris,
thanks, I appreciate your help
-----------------
1. Install CentOS 7.0 to vda
2. reboot
3. btrfs dev add /dev/vdb /
4. reboot
## works
5. btrfs balance start /
6. reboot
## works
Same thing when starting with CentOS 7.2 media.
This is a NAS product using CentOS 7.2? My only guess is they've
changed something broke this.
-----------------
I confirm that it runs also for me on CentOS 7 Minimal. Thus we can rule out
CentOS and myself as the Source of the problem.
Rockstor is Based on Centos 7.2.
So, I compared the grub.cfg of Centos 7.2 -which works for me to Rockstor.
I see very few differences apart from UUIDs:
1) menuentry 'Rockstor' --class rhel fedora
menuentry 'Centos ' --class centos
2) insmod ext2
insmod zfs
I have attached the two files.
Can you point me at other settings/files I could compare, please?
Regards,
Hendrik
