LVM + Couldn't create temporary archive name
we have 100% on /
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg08_root 20G 20G 132K 100% /
so when I do lvextend we get the following errors
# lvextend -L+5G /dev/mapper/vg08_root
Couldn't create temporary archive name.
Volume group "vg00" metadata archive failed.
how to resolve this?
It is because there is no space in the /etc/lvm/archive or it is read only.
Judging with the partition being 100% full, /etc/lvm/archive has no space left. You will have to create some space in the root partition.
If it still does not work, means that the folder is read-only. Resolve using : chmod a+r /etc/lvm/archive
You may be able to circumvent the space requirement for this operation by disabling the metadata backup with the -A|--autobackup option:
lvextend -An -L+5G /dev/mapper/vg08_root
If you do this, follow the operation with a vgcfgbackup to capture the new state.
Post-mortem note:
Since the ultimate goal was to expand the logical volume and resize the encapsulated filesystem, a one-step operation could have been used:
lvextend -An -L+5G --resizefs /dev/mapper/vg08_root
In this case, the filesystem type would have been automatically deduced, avoiding trying to use resize2fs in lieu of `xfs_growfs’.
