I have a really weird problem. After changing the mount point of a Linux
ext3 fs to a different device, the mount point disappears after mounting
and is inaccessible.
Disk layout:
ad4s1 Linux ext3
ad4s2 FreeBSD
ad4s3 Linux ext3
ad4s4 ext
ad4s5 Linux swap
ad4s6 Linux ext3
ad4s7 Linux ext3
ad4s8 Linux ext3
Mounting ad4s7 under FreeBSD as
/dev/ad4s7 /gentoo-portage ext2fs rw 0 0
Then I moved this data to ad4s8 and changed the fstab entry accordingly:
/dev/ad4s8 /gentoo-portage ext2fs rw 0 0
And this happens:
[root@jeanie ~]# cd /
[root@jeanie /]# ls
.cshrc cdrom etc mnt tmp
.profile compat gentoo-portage proc usr
.snap dev home rescue var
COPYRIGHT dist lib root
bin distfiles libexec sbin
boot entropy media sys
[root@jeanie /]# mount /gentoo-portage
[root@jeanie /]# df

I changed the filesystem on /dev/ad4s8 to ext2, but the problem persists.
No idea what's going on :-/
