I have two filesystems in a pool, backup/nextcloud and backup/vm. Today, after a send/receive transfer was interrupted before it could finish (I was backing stuff up to these filesystems), I no longer see backup/vm, but the space it was taking up is still not freed up (and therefore I hope it can be easily brought back).
zfs list output:
NAME USED AVAIL REFER MOUNTPOINT
backup 613G 2.91T 104K /backup
backup/nextcloud 613G 2.91T 607G /backup/nextcloud
zpool status:

I've tried rebooting, reimporting, and everything similar sanity passes, but to no avail.
Edit: added zfs history backup output
What could be done to bring back the filesystem? (zfs version 2.0.3_5.11.1.arch1.1-1)
