Consider switching to journaled quota to avoid running quotacheck after an unclean shutdown.

Hello, I recently did run the command "/scripts/fixquotas" to fix the disk space reported by CPanel accounts and got the following responses. Can you help me to understand them? [root@s2 ~]# /scripts/fixquotas journaled quota support: kernel supports, user space tools supports (available) /dev/sda (already configured quotas = 1). /dev/disk/by-id/scsi-0Linode_Volume_home2 (already configured quotas = 1).
