why ext3 change to rootfs ??

jiawj · 02-01-2005, 10:10 PM

when i start and into my RHAS3-U2 box, I find my /etc/mtab is:
[root@rh3u2 root]# mount -l
rootfs on / type rootfs (rw)
/dev/root on / type ext3 (rw)
/proc on /proc type proc (rw)
none on /dev/pts type devpts (rw)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
none on /dev/shm type tmpfs (rw)
/dev/sdb3 on /mnt/hd type ext3 (rw) []

why my ext3 filesystem change to rootfs ?

my /etc/fstab is:

Quote:

LABEL=/ / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/sda3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

Hi

When you enter the 'df -Th` command what is the fs type for / ????????

df -h

rootfs 7.7G 5.8G 1.6G 79% /

Hi Please use the "-T" to see filesystem
