Hi, freebsd users.
I have found a strange bug when erroneously change my fstab file.
In time of next reboot on final stage, when mounting partitions
I have fairly recived this message:
mountroot> ufs:/dev/ad1s3a
Mounting root from ufs:/dev/ad1s3a
Root mount failed: 22
Manual root filesystem specification:
<fstype>:<device> Mount <device> using filesystem
<fstype>
eg. ufs:/dev/da0s1a
? List valid disk boot devices
<empty line> Abort manual input
ad1s3a is my mistake. Root is on ad1s2a so..
mountroot> ufs:/dev/ad1s2a
Root mount failed: 22
Manual root filesystem specification:
<fstype>:<device> Mount <device> using filesystem
<fstype>
eg. ufs:/dev/da0s1a
? List valid disk boot devices
<empty line> Abort manual input
Then I just reboot with "boot kernel.GENERIC", do the same thing and
have a single user mode. I have done it many times to avoid mistakes.
Here some information about my system:
> ls -l kernel kernel.GENERIC
-r-xr-xr-x 1 root wheel 2842857 17 feb 15:35 kernel
-r-xr-xr-x 1 root wheel 4028952 9 oct 2002
kernel.GENERIC> uname -r
4.9-STABLE
Src was cvsupd 12/02/2004 and kernel build 17/02/2004.
I have found some information in maillist archive and have thought that
it probably the same:
http://www.mail-archive.com/freebsd-stable@freebsd.org/msg59577.html
There may be some bugs in my kernel config so here it is...
Best regards,
Nikolay Pavlov. Sorry for my english.
