Description Andy Grover 2017-02-09 22:58:27 UTC
When one uses XFS on thinp, there are a number of issues that arise:

One is just that the 'df' utility doesn't return relevant information about the space actually available to the filesystem.

Two, there may not be sufficient coordination between the two layers when running low on space in the thin pool.

Three, it's not clear (at least to me) the degree which being on thinp affects XFS performance characteristics, and how efficient XFS is in resisting fragmentation and inefficient usage of thinp blocks. It would be good to analyze and possibly improve XFS's behavior in this area.

Comment 1 Fedora End Of Life 2017-02-28 11:14:10 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle.
Changing version to '26'.

Comment 2 Fedora End Of Life 2018-05-03 08:03:37 UTC
This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
