XFS Developer Takes Shots At Btrfs, EXT4

[ortango]

I kinda just agree with susikala. Esp after the fsck.btrfs announce, seems like just drama.
XFS is great for some things (that overlap with what btrfs hopefully will be even better at _in the future_). For now I am psyched about XFS improvements -- which is what I thought the talk was about. Why? Because XFS is infinity more reliable right now, and I use it. It would not be news to say that the ext4 has shortcomings and btrfs is still in serious development.
In essence what I am saying is that at least the only thing that Mason or Chinner have killed is ext4. ;-P hey where is reiser4 anyway ;-P

That's great if it truly is fixed. But I find it strange that even in 2011 some people complain about it. http://www.linuxquestions.org/questi...earing-919115/

Which is big-iron systems. How much testing does EXT4 have of exabyte file systems? Multi-terrabyte files spread across dozens of disks in RAID?

Probably quite a bit less than XFS.

But it's clearly not true if you are talking about desktop systems.

Does XFS support shrinking the filesystem already? Granted, that need doesn't arise often, but is still quite handy when reorganising partition layout..

This. Even though JFS was designed for "huge" FS too, I understand it was only run on such with AIX, and so the linux jfs tools could not cope with >16tb until somewhat recently.

I've been very happy running XFS on several production servers, laptops, and workstations over the past few years. The performance improvements are very noticeable. Keep up the good work!

BLOODY HELL! You "find it strange" when people don't unmount their file systems before rebooting and discover errors!

I would "find it strange" if that user did NOT experience severe problems!

My mind boggles that ext4 filesystems STILL are not supported with ext-tools for filesystems larger than 16TB..

This is not true anymore.

Not sure if serious... Distro shutdown scripts, called when you run "reboot", sync and umount disks.

called when you run "reboot".

Did you READ the original post?

[ 10.369694] XFS mounting filesystem md127
[ 10.821454] Starting XFS recovery on filesystem: md127 (logdev: internal)
[ 26.103306] Ending XFS recovery on filesystem: md127 (logdev: internal)

These messages would NOT be printed at boot time if the filesystem was unmounted.
