jails py39-iocage-1.2_10 export returns non-zero status

[byrnejb]

When I attempt to export a stopped iocage managed jail I am getting this error:

#  iocage export mx132&
[1] 80640
[root@vhost03 ~ (master)]# Exporting dataset: zroot/iocage/jails/mx132
Exporting dataset: zroot/iocage/jails/mx132/root
warning: cannot send 'zroot/iocage/jails/mx132/root@ioc-export-2023-11-23': Input/output error
Command '['zfs', 'send', 'zroot/iocage/jails/mx132/root@ioc-export-2023-11-23']' returned non-zero exit status 1.

What do I do to determine why this is happening?

I have successfully exported a different jail on the same host.

Maybe need to check ZFS status?
zpool status -v

Try sending that snapshot to /dev/null, just to check if the snapshot itself is still good. It might be corrupted or have some other issue that causes it to fail.

Something like: zfs send zroot/iocage/jails/mx132/root@ioc-export-2023-11-23 > /dev/null

thanks. I had to move on due to time constraints and cannot do further testing.
