SOLVED iocage UUID too long for fstab

[Richard Brouwer]

I have been mucking around with iocage and running into problems mounting host shares. When I try:
iocage fstab -a /path/to/the/share

I get

RuntimeError: mount_nullfs: /mnt/iocage/jails/a0a5e528-0198-4342-8058-490e549cc0a8/root/mnt/brouwerNAS/family_movies: File name too long
jail: /sbin/mount -t nullfs -o ro /mnt/brouwerNAS/family_movies /mnt/iocage/jails/a0a5e528-0198-4342-8058-490e549cc0a8/root/mnt/brouwerNAS/family_movies: failed

on starting the jail.

It seems to me that the UUID for the jail is too long so can't mount shares. How can I make the UUID shorter in an existing jail - or a new jail even so I can get stuff mounted.

Try to add -s when using iocage create.

iocage has its own way of mounting shares. Use # iocage fstab -a <jail> /path/to/share. That will mount your share to the jail in read only. You can edit your iocage fstab using # iocage fstab -e <jail>

@scrappy the OP explicitly stated that he was using iocage fstab -a ...

Oops, you're absolutely right. Can't believe I glossed over that. One thing I noticed after reading the first part of the OP is that he/she didn't list the jail name before the share to be mounted.

I've played with iocage quite a bit and never had problems adding storage. As has been previously stated, # iocage fstab -a JAILNAME /the/dir will nullfs mount "/the/dir" into the jail as "/the/dir".

You can also use # iocage fstab -a JAILNAME "/the/source/host/dir /the/dest/dir/in/the/jail nullfs ro 0 0" if you want to specify a particular destination in your jail. And you can replace the ro with rw if you want read/write capability for the mounted volumes.

Replace JAILNAME with the name you assigned to the jail (does not have to be the uuid.)

Thanks for all the advice. Using -s when creating the jail did the trick - a shorter UUID makes things neater imho!

I did use my JAILNAME with iocage fstab - sorry I left it out in my original post.

This is due to FreeBSD versions prior to 12 having an fstab path name limit of 88 characters. With the added overhead of iocages you effectively have an iocage's fstab path character limit of 28:

iocage fstab entries have effective maximum path length of 28 characters
