raid 5 from 3 disk to 4 disk

F5-422 TOS 4.2.39
Several days I created a raid 5 with three 2TB drives. Everything went great.
Yesterday I add 4th 2TB disk drive. I waited a day for it to sync. The 4th disk shows and it's in the pool. The pool size has increased in space.
The volume size never increases. I clicked on max size but it does not seem to do anything.

Please refer to this to increase your volume size manually:

The link you provided shows a bunch of commands to enter at the command line.
Does that mean this software is broken and just for show? Is it not going to be fixed because TOS 5 is out?

In theory, since TOS5 has better storage management, it is possible to fix this problem after reinstalling to TOS5. But we haven't actually tried to do that yet.

I will just add a few notes in case anyone searches and has this problem.
The umount command does not work because the filesystems are busy. You can try lsof but since you logged in as a user /home will always be busy. There is not way to boot to single user mode and have console access that I know of.
My insecure work around was to allow root to ssh onto the machine because it's home dir is on / instead /home which is part of the lvm you are trying to extend.
man/google/duckduckgo root login access
vi /etc/ssh/sshd_config
PermitRootLogin yes
AllowUsers Sean root
restart sshd or reboot
After you umount the two file systems in the instruction; the rest instructions they supplied work.

Hi Did moving to TOS 5 resolved the issue?
