gentoo linux, kernel 3.10.31 mount options bug?

[Marko Weber|8000]

hello list,

i have a question about mount options.

at first my fstab:

/dev/md0                /boot           xfs             noauto,noatime  
1 2
/dev/md2                /               xfs             
noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep      
0 1
/dev/md1                /tmp            xfs             
noexec,noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep 
       0 1
/dev/VolGroup01/var-www /var/www        xfs             
noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep      
0 1
/dev/VolGroup01/var-log /var/log        xfs             
noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep      
0 1
/dev/VolGroup01/var-lib-mysql   /var/lib/mysql  xfs             
noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep      
0 1
/dev/sda5               none            swap            sw,pri=1         
        0 0
/dev/sdb5               none            swap            sw,pri=2         
        0 0

(YES!, normally i use Label or UUID..... but this is only a test 
machine.....)


AFTER reboot "mount" shows this:

rootfs on / type rootfs (rw)
/dev/root on / type xfs 
(rw,noatime,nodiratime,attr2,nobarrier,inode64,noquota)
/dev/md1 on /tmp type xfs 
(rw,noexec,noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep)
/dev/mapper/VolGroup01-var--www on /var/www type xfs 
(rw,noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep)
/dev/mapper/VolGroup01-var--log on /var/log type xfs 
(rw,noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep)
/dev/mapper/VolGroup01-var--lib--mysql on /var/lib/mysql type xfs 
(rw,noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep)


on /dev/root "discrad" and some other are not shown


when i do a "mount -o remount /"

"mount" shows this:


rootfs on / type rootfs (rw)
/dev/root on / type xfs 
(rw,noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep)
/dev/md1 on /tmp type xfs 
(rw,noexec,noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep)
/dev/mapper/VolGroup01-var--www on /var/www type xfs 
(rw,noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep)
/dev/mapper/VolGroup01-var--log on /var/log type xfs 
(rw,noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep)
/dev/mapper/VolGroup01-var--lib--mysql on /var/lib/mysql type xfs 
(rw,noatime,nodiratime,nobarrier,largeio,discard,logbsize=256k,noikeep)

now,all options from /etc/fstab are listed.
Is this XFS related?

Kernel 3.10.31
Grub2

in the /etc/grub.d/40_custom i have set:


menuentry "gentoo linux 3.10.31" {
insmod xfs
insmod mdraid09
insmod mdraid1x
insmod lvm
set root=(hd0,2)
linux /bzImage-3.10.31 root=/dev/md2 elevator=cfq clocksource=hpet 
cgroup_disable=memory
}


If you need any more info, let me know.
