    ZFS SLOG device with no performance effect?

    Greetings, I have a sort of backup server for snapshots. This server is only dedicated to receive snapshots. There is no NFS/FTP/.... . During a transfer of a snapshot using netcat I added a slog NVMe ssd to the backup pool. I was hoping to see even a tiny speed boost, but there was none. I...

    ZFS zfs Snapshot of FileSystem Doesn't Contain Data of FileSystems Below It

    Question. I have a zpool called "zjail", with a zfs file system mounted on it at /zjail. Other file systems are created and mounted at /zjail/jail1 /zjail/jail2 etc. So zfs list -t all looks something like this: root@dom0:~ # zfs list -t all | grep zjail zjail 2.08G...

    ZFS Clarification on "filename path" limitation for ZFS snapshot mounts in 11.xR, until ino64 lands

    This question is related to the 63-or-88 char limit on mount paths as it affects ZFS snapshots, this 11.1R part-resolution in r319096, this issue + this. To recap as I understand it, up to 11.0R, file system actions that implicitly needed to mount ZFS snapshots were limited by statfs's fixed...

    ZFS send/recv via ssh hangs

    I was using the send/recv ZFS command to upload snaphots from a server to another via ssh. There were no issue while both were running 10.3-RELEASE. But, since I upgraded the receiver to 11-RELEASE, the process hangs while sending or receiving the 2nd set. First set, root@mySnap is well...
