No XFS support in Xenial vanilla?

[KodiakFi]

Any reason why an XFS kernel driver isn't included in the Armbian images?  I'm coming from the RHEL world so I have no idea if it's common for Debian and it's variants to not have XFS support?  I'm kind of baffled.

Coming with next update or if you DIY.

Filesystem support is a kernel thingie and not that much related to 'Debian' since Armbian does not rely on Debian's kernel packages but uses its own variants (on most platforms supporting 2 variants -- legacy and vanilla --  and on all containing a lot of fixes/improvements).

 

And there's a pretty good reason that XFS support is disabled in nearly every kernel source tree around we're using: since it led to data corruption and failures back in the days when the 'Linux on ARM' game started (almost a decade ago in the 2.6.x days). So we enable XFS on a 'per request' basis and hope that the person asking for does at least some basic testing and get back to us if problems occur.

Its had a history of corrupting data that predates that too. Earlier versions of the xfs fsck-equivalent would take anything that looked like inode information regardless of position in the filesystem and would happily "repair" data inside of disk images, etc.

Interesting.  I'm coming from the Red Hat world where it's become the default filesystem (RHEL 7 and beyond); with RHEL 6 we defaulted to EXT4. 

 

I will just stick with EXT4 on ARM for now.  Thanks for all the information, everyone!
