[ale] [EXTERNAL] Re: xfs vs. ext4

[Allen Beddingfield]

We use XFS almost exclusively.  When SUSE started pushing BtrFS a few years back, we rolled out a few systems with that, and quickly just went back to XFS for everything.  Anecdotal point of data:  We had two events where we lost storage connectivity to our 1500+ VM VMware setup.  In both cases, not a single XFS system had a problem.  All the ext3 and ext4 systems had to have some sort of attention, and one BtrFS system was not repairable.

XFS is still under active development at HPE. We put it on clusters and big storage as CXFS.

HPE may have bought us but there are still a lot of the same people working on it.

I thought ZFS was the one with the brightest future?

I do realize that there's six high quality linux journaling filesystem projects for linux (high quality but not necessarily high quality on linux as in the case of AdvFS):

ReiserFS (this project was killed, no pun intended)
SGI XFS
DEC AdvFS, never went anywhere, ported to hpux, source is available
IBM JFS
ZFS, still chugging along and is starting to be used in some places, freenas/truenas, QNAP's QuTS appliance etc...
EXT4, known to be used at Google afaik, public talks mention it's use due to the upgrade path from their historical EXT2 usage (I previously worked at Google as smart hands and a network operations engineer, but I did not see into their systems at this level)

Did I miss any?

It also deals much better with large files than ext (e.g. on a DVR like
Mythtv).  I put XFS onto my newest Myth Backend and it's working very
well.

I use JFS for that. Mainly because fscks and deletes are super fast. It's also a nice file system for large files.
