Re: [Kernel-packages] [Bug 1838276] Re: zfs-module depedency selects random kernel package to install
Would turning the hard dependency into a somewhat softer recommendation be a possible solution? Do zfsutils require the module to be actually installed, or would rw access to /dev/zfs suffice?

I traced this back to 193fb6a2c94fab8eb8ce70a5da4d21c7d4023bee (merged
in 4.4.0-6.21), which added a second parameter to lookup_bdev without
patching the zfs module (which needs to special case the vdev-on-zvol
case, and uses this exact method only in this special casing code
path).
attached you can find the output of "zfs send -R" ing such a zvol
("brokenvol.raw"), running "zfs receive POOL/TARGET < FILE" followed
by "zpool import" should reproduce the hang.

[Kernel-packages] [Bug 1636517] Re: zfs: importing zpool with vdev on zvol hangs kernel
Colin, thank you for the fix, I will switch to xenial-proposed now.
As a followup, upstream merged my PR so 1014-kernel-lookup-bdev.patch
may be removed once the next ZFS on Linux release gets synced to us,
hopefully in time for zesty.

[Regression Potential]
Minimal. This just touched one line in the zfs module

Tested and passes with the ubuntu kernel team autotest client zfs
regression tests.

Re: [Kernel-packages] [Bug 1639963] [NEW] zfs get compressratio returns bogus results
ZFS works as intended, here. Zero-filled blocks are not counted into the compression ratio, as they get dismissed early in the compression pipeline and never hit the disks as used data: # zfs create sbblht/test # dd if=/dev/zero of=/test/a bs=16M count=8 8+0 records in 8+0 records out 134217728 bytes (134 MB, 128 MiB) copied, 0.0718708 s, 1.9 GB/s root@sbooblehat:~# du -shx /test/ 1.0K/test/ root@sbooblehat:~# du -shx --apparent-size /test/ 129M/test/ # zfs list -o used,logicalused,ratio sbblht/test USED LUSED RATIO 19K 9.50K 1.00x -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1639963 Title: zfs get compressratio returns bogus results Status in zfs-linux package in Ubuntu: Invalid Bug description: I'm running a just-installed-today copy of 16.04.1, installed from an ISO also just downloaded today from releases.ubuntu.com. root@xenial:~# lsb_release -rd Description: Ubuntu 16.04.1 LTS Release: 16.04 root@xenial:~# apt-cache policy zfsutils-linux zfsutils-linux: Installed: 0.6.5.6-0ubuntu14 Candidate: 0.6.5.6-0ubuntu14 Version table: *** 0.6.5.6-0ubuntu14 500 500 http://us.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages 100 /var/lib/dpkg/status 0.6.5.6-0ubuntu8 500 500 http://us.archive.ubuntu.com/ubuntu xenial/universe amd64 Packages I noticed that zfs get compressratio was not returning good results, and tested to ensure it was the compressratio reporting that was broken, not the actual compression.

We should be seeing a compressratio of about 3.41x. root@xenial:~# zfs get compressratio data/test NAME PROPERTY VALUE SOURCE data/test compressratio 1.01x - But we're seeing 1.01x.
