Poudriere: How to Clean up a Dropped SSH Session During a Build?

Hello FreeBSD Forums,

I'm having some issues cleaning up after a "failed" poudriere build. To summarize, I initiated a poudriere bulk over an ssh connection, and the network connection was interrupted. When I was able to ssh back into the machine running poudriere, none of the build processes were running, but all of the build files were still there.

I attempted to remove the poudriere jail using poudriere jail -d -j 13amd64, thinking this would free up the most recent build environment so I could run poudriere bulk again. However, during the process I noticed that there were a lot of errors; specifically, where the removal of files were not able to be completed since they were mounted as read-only. An excerpt is below:

Code:
rm: /pool/var/poudriere/data/.m/13amd64-server/05/usr/ports/audio/midifile: Read-only file system
rm: /pool/var/poudriere/data/.m/13amd64-server/05/usr/ports/audio/miniaudio/pkg-descr: Read-only file system
rm: /pool/var/poudriere/data/.m/13amd64-server/05/usr/ports/audio/miniaudio/Makefile: Read-only file system
rm: /pool/var/poudriere/data/.m/13amd64-server/05/usr/ports/audio/miniaudio/distinfo: Read-only file system

I interrupted the removal process using [CTRL][C]. After this point, any attempt to remove the jail using the previous command will report there is no such jail.

However, using jls, I can see a list of jails with the jail name combined with the port tree name. Again, an excerpt is below.:

JIDIP AddressHostname Path
31127.0.0.1build-host. /pool/var/poudriere/data/.m/13amd64-server/ref
32build-host./pool/var/poudriere/data/.m/13amd64-server/ref
33127.0.0.1build-host./pool/var/poudriere/data/.m/13amd64-server/06
34build-host./pool/var/poudriere/data/.m/13amd64-server/06


So far I haven't been able to figure out from the man pages how to remove these jails using either `jls` or the `jail` commands. I'll be looking closer to determine how and post here if I figure it out.

Other ways I attempted to remove the jail used the follwing commands, which also both failed.

Code:
zfs destroy -R pool/poudriere/jails/13amd64
cannot unmount '/pool/var/poudriere/jails/13amd64': unmount failed

Code:
umount pool/poudriere/jails/13amd64
umount: unmount of /pool/var/poudriere/jails/13amd64 failed: Device busy

Right now I'm at a loss of what to do next. What I want to do is to clean up the mess I've made so far, re-create the jail, and start building the packages again for my systems. For the next time I attempt to build over a wireless or remote connection, I'll try to use tmux before starting the job so I can pick up where I left off with the build rather than repeating this painful process.

Normally, poudriere cleans up itself on termination (and SIGPIPE should terminate), so you were a bit unlucky.

You will have some null-mounts inside the jails poudriere creates. List them with mount and unmount them manually, after that, removing the jail should work.

To avoid these problems in the future, always run poudriere e.g. inside sysutils/tmux.

For poudriere, I think that should be mentioned in the FreeBSD handbook, probably at 4.6.1. Initialize Jails and Port Trees or just preceding it.

Something like:
When remotely controlling a poudriere build (for example via SSH), the connection might get interrupted and break the current poudriere build process. Please consider an appropriate tool for remotely controlling a poudriere build that allows you to reconnect to an interrupted connection. For example sysutils/tmux or sysutils/screen
It may even be worth considering elevating such a text; e.g. in an Important or Note text block.

Ah, the nice thing about Poudriere is that it can survive even a reboot. You can kill the process, and whatnot, reboot the machine, and then just restart your poudriere-bulk(8) command. It will pick up where it left off, as though nothing happened. The only thing to pay attention to is the filepath to the list of ports that you feed to poudriere-bulk(8) ;)

I have a small script destroying the hung zfs datasets:

cat zfs_destroy
Code:
zfs destroy -f -R ZT/jails/a/apou/jails/ap-ports-ref/01
zfs destroy -f -R ZT/jails/a/apou/jails/ap-ports-ref/02
zfs destroy -f -R ZT/jails/a/apou/jails/ap-ports-ref/03
zfs destroy -f -R ZT/jails/a/apou/jails/ap-ports-ref/04
zfs destroy -f -R ZT/jails/a/apou/jails/ap-ports-ref/05 
zfs destroy -f -R ZT/jails/a/apou/jails/ap-ports-ref/06

I followed Ziria's advice and attempted to remove the null mounts listed. There were a ton of mount points:

I attempted the first one, and umount reported the device as busy.

Code:
root@xxx:/home/localuser # umount /pool/var/poudriere/jails/13amd64/rescue
umount: unmount of /pool/var/poudriere/data/.m/13amd64-server/ref/rescue failed: Device busy

I assumed that the others would be like this as well. Since I'm the only person who uses the serivces of this machine, I rebooted the FreeBSD machine via shutdown -r now.

After reboot, there were a lot less mountpoints for poudriere:

Code:
pool/poudriere on /pool/poudriere (zfs, local, nfsv4acls)
pool/poudriere/data on /pool/var/poudriere/data (zfs, local, noatime, nfsv4acls)
pool/poudriere/data/packages on /pool/var/poudriere/data/packages (zfs, local, noatime, nfsv4acls)
pool/poudriere/jails on /pool/poudriere/jails (zfs, local, nfsv4acls)
pool/poudriere/jails/13amd64 on /pool/var/poudriere/jails/13amd64 (zfs, local, noatime, nfsv4acls)
pool/poudriere/ports on /pool/poudriere/ports (zfs, local, nfsv4acls)
pool/poudriere/ports/server on /pool/var/poudriere/ports/server (zfs, local, noatime, nfsv4acls)
pool/var/poudriere-base on /pool/var/poudriere-base (zfs, local, nfsv4acls)

I attempted to remove the 13amd64 jail manually using poudriere jail -d -j 13amd64, but as before this errored out with no such jail.

I then attempted to remove manually using rm:

Code:

Eternal_Noob and Sir Dice made a post to alter the system immutable flag, which I used below:
Code:
root@xxx:~/poudriere # chflags -R noschg /pool/var/poudriere/jails/13amd64

I then got an error that the device was already busy:
Code:
root@xxx:~/poudriere # rm -rf /pool/var/poudriere/jails/13amd64
rm: /pool/var/poudriere/jails/13amd64: Device busy

Figuring it was another mount point, I referred to the previous mount points above and used zfs destroy to remove the underlying strucutre:
Code:
root@xxx:~/poudriere # zfs destroy pool/poudriere/jails/13amd64

I then attempted to create the jail again. Poudriere didn't like there was a directory with that name already present:
Code:
root@xxx:~/poudriere # poudriere jail -c -j 13amd64 -v 13.0-RELEASE
[00:00:00] Error: Directory /pool/var/poudriere/jails/13amd64 already exists

So I removed it:
Code:
root@xxx:~/poudriere # rm -r /pool/var/poudriere/jails/13amd64

Which enabled me to finally create the jail:

Code:
root@xxx:~/poudriere # poudriere jail -c -j 13amd64 -v 13.0-RELEASE

Now, I'm using tmux() happily now on my remote machine that's building packages, and will test out its resilience by intentionally breaking network connection and seeing what happens.
