Correct Way to expand ZFS?

[Albert Yang]

Hi
I was wondering if someone could shed currently wanted to know whats the correct way to expand a zfs pool these are the steps i normally take

apt-get install parted
zpool set autoexpand=on data2

then i delete the partition 9 not sure why i have to run it twice as the first time fails

root@dockers:~# parted /dev/sdb rm 9
Warning: Not all of the space available to /dev/sdc appears to be used, you can fix the GPT to use all of the space (an extra 104857600 blocks) or continue with the current setting?
parted: invalid token: 9                                                 
Fix/Ignore? fix                                                           
Error: primary partition table array CRC mismatch
root@dockers:~# parted /dev/sdb rm 9                                     
Information: You may need to update /etc/fstab.

then

parted /dev/sdb resizepart 1 100%
zpool online -e data2 /dev/sdb

i do see that it expands but i find it odd the delete portion part

The usual way:

zpool set autoexpand=on pool
zpool replace olddisk newdisk

When all disks are replaced with larger ones, capacity is increased

thanks for the reply, so there is no need to delete part 9 ?
forgot to mention im doing it on a test server VM

in the VM i have zfs raid 0 with 1 virtual disk.

then i turn off the vm i expand the disk start the vm again

so all i would need to do would be zpool set autoexpand=on pool

Thank you

In case you've allocated the whole disk for ZFS (not only one partition) and parameters, mentioned by Gea are in place, then during import of the pool new size will be reflected.
