I've a interesting situation. I've created two pool now and one pool
named "Data" and another named "raid5". Check the details here:
bash-3.00# zpool list
NAME SIZE USED AVAIL CAP HEALTH
ALTROOT
Data 10.7T 9.82T 892G 91% ONLINE -
raid5 10.9T 145K 10.9T 0% ONLINE -
As you see, the sizes are approximately the same. If I run the df
command, it reports:
bash-3.00# df -h /Data
Filesystem size used avail capacity Mounted on
Data 11T 108M 154G 1% /Data
bash-3.00# df -h /raid5
Filesystem size used avail capacity Mounted on
raid5 8.9T 40K 8.9T 1% /raid5
You see that the Data has 11 TB when zpool reported 10.7 TB and the
raid5 has 10.9TB in zpool but only 8.9 TB when using df. Thats a
difference of 2 TB. Where did they go?
To your raid5 (raidz) parity.
Check 'zpool status' to see how your two pools differ.. zpool list
shows
the disk space you have.. zfs/df shows how much you can store there..
