hi all: When I install ovirt-node, after two days I found this version by the question and I have some local storage of data on the inside, I want to upgrade ovirt-node, but I found the following error. all Hacker, please help me out a good idea... [Errno 30] Read-only file system: 'liveos/grub' Traceback(most recent call lash): File "/usr/libexex/ovirt-config-installer". line 1087 in start self.upgrade_node() File "/usr/libexex/ovirt-config-installer". line 886, in upgrade_node() boot_setup = install.ovirt_boot_setup() File "/usr/lib/python2.6/site-paceages/ovirtnode/install.py", line 391, in ovirt_boot_setup File "/usr/lib64/python2.6/os.py", line 157 in makedirs OSError:[Error 30] Read-only file system: '/liveos/grub' I at least tried mounting the LABEL=Root partition to /liveos, I was told it is busy, but I couldn't find out why it was busy, because I ran into the squashfs errors, which appeared indmesg as soon as I used tools like findmnt etc.
