I’m actually heavily testing ZFS On Linux. As hard drive, I’m using a volume from LVM (named data-zfs2) :<\/p>\n

 NAME STATE READ WRITE CKSUM\r\n backup ONLINE 0 0 0\r\n   data-zfs2 ONLINE 0 0 0<\/pre>\n
 <\/p>\n
But my volume is now nearly full :<\/p>\n
[10:31:23]root@direct:~$ zpool list\r\nNAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT\r\nbackup 599G 584G 15.2G 97% 1.00x ONLINE -<\/pre>\n
So first, let’s tell ZFS to auto-expand :<\/p>\n
zpool set autoexpand=on backup<\/pre>\n
And now,\u00a0extend the volume underneath :<\/p>\n
lvextend -L +100G data\/zfs2<\/pre>\n
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert\r\nzfs2 data -wi-ao---- 700.00g<\/pre>\n
Let’s see what zpool is now reporting :<\/p>\n
zpool list\r\nNAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT\r\nbackup 599G 584G 15.2G 97% 1.00x ONLINE -<\/pre>\n
Not good \ud83d\ude41<\/p>\n
You need to \u00ab\u00a0refresh\u00a0\u00bb the device :<\/p>\n
zpool online backup data-zfs2<\/pre>\n
And now :<\/p>\n
zpool list\r\nNAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT\r\nbackup 699G 584G 115G 83% 1.00x ONLINE -<\/pre>\n
