Workaround for shrinking a XFS CentOS root partition
Clash Royale CLAN TAG#URR8PPP
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty margin-bottom:0;
I run a cloud VPS with Centos 7 installed. Unfortunately, I could not customize disk partitions during installation so now I have no free space in the volume group automatically created because it is completely used by two logical volumes: swap and root.
I would like to reduce root size and create some space for managing LVM snapshots but I know that on XFS file systems there are no chances to shrink a partition.
Can I do anything?
The server is currently in production, so I cannot reinstall the system, but even so, I could not customize partitions because it is an automatic procedure.
Thank you.

Is your swap LV large enough to contain the files in your rootfs? Do you have enough RAM to go without swap for a little while? If so, you can: temporarily disable swap, delete the swap LV, create a new LV, copy your rootfs to it, reboot using the new LV as your rootfs, enlarge the new LV and the rootfs, recreate the swap LV and activate it.

@EmmanuelRosa negative Sir, root lv is used for about 9GB while swap is only roughly 2GB.
