To: Xfs
hello list,
my drives are all xfs formatted.
in fstab i set:
lazytime,logbsize=256k,logbufs=8
when i call "mount" on console i get:
rw,relatime,lazytime,attr2,inode64,logbufs=8,logbsize=256k,sunit=1024,swidth=3072,noquota
Why is relatime listed? Or is lazytime override this setting?
Even when i set "norelatime" in /etc/fstab i get "relatime" listed on
'mount'
Or am i wrong here with this question? is this not xfs related?
anyway, for any hints or suggestions i am thankful
best regards
marko

Probably depends on the distribution. I know that on openSUSE you get relatime set, for instance. -- Cheers / Saludos, Carlos E. R.

I'm guessing this is your root fs? xfs today will silently ignore unknown mount options on remount (patches to fix that are upstream), and the root fs may get remounted w/ fstab options. So presumably that's how you got lazytime into the mount output, especially if it's looking at /etc/mtab.

So on everything but ext4 it does nothing, it conflicts with other atime settings we do support, and we can't really do anything about it...
