Slow zfs destroy
Hi! Is it normal that "zfs destroy" for one ZVOL with attribute "used" equal to 2112939808 bytes (~2GB) takes over two minutes waiting on "tx_sync_done_cv"? The pool is RAID1 over five SSDs encrypted with GELI having ZIL and Cache on distinct unencrypted SSD. 11.3-STABLE/amd64 r354667. System has 360G RAM and vfs.zfs.arc_max=160g. ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

Re: Slow zfs destroy
As you mentioned it’s on SSD you could be suffering from poor TRIM performance from your devices if you run gstat -pd you’ll be able to get an indication if this is the case.
