Folks I'm trying to use xfs_quota to keep track of disk space usage for my users. The documentation states that I should specify "uquota" as an option on the mount data in /etc/fstab. Yet, I cannot find the entry in fstab that corresponds to the Logical Volume that ends up being mounted on /home1. The system in question was installed on a single disk system. Later, after install, I added a second disk, created a Logical Volume on it, and mounted it as /home1, where all the user data gets stored. It holds an xfs file system. Upon examining /etc/fstab, there's no evidence of the second disk, yet it does get mounted: [root at ape ~]# cat /etc/fstab # # /etc/fstab # Created by anaconda on Fri May 1 21:05:38 2020 # # Accessible filesystems, by reference, are maintained under '/dev/disk/'. # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info. # # After editing this file, run 'systemctl daemon-reload' to update systemd # units generated from this file. # /dev/mapper/cl_ape-root / xfs defaults 0 0 UUID=d5a206d6-7ea1-42b7-8f52-071e98d09f98 /boot ext4 defaults 1 2 /dev/mapper/cl_ape-swap swap swap defaults 0 0 [root at ape ~]# Yet, when I look at the current mounts of xfs file systems: [root at ape ~]# mount | grep xfs /dev/mapper/cl_ape-root on / type xfs (rw,relatime,attr2,inode64,noquota) /dev/mapper/vg_abcde-lv01 on /home1 type xfs (rw,relatime,attr2,inode64,noquota) [root at ape ~]# the LV of the second disk shows up. lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 25G 0 disk +-sda1 8:1 0 1G 0 part /boot +-sda2 8:2 0 24G 0 part +-cl_ape-root 253:0 0 21.5G 0 lvm / +-cl_ape-swap 253:1 0 2.5G 0 lvm [SWAP] sdb 8:16 0 5.2T 0 disk +-vg_abcde-lv01 253:2 0 5.2T 0 lvm /home1 sr0 11:0 1 597M 0 rom [root at ape ~]# How do I enable quotas on a file system that is being mounted but not in fstab? I suspect systemd has a role here, but I can't find any evidence. David
