fsck doesn't work - not even run?
Hi,
please consider, I'm pretty new to HP-UX, thanks.
Our server (rp7420 with HP-UX 11.31) has crashed due to disk write error (not boot partition). So I replaced damaged device with the new one of the same size and performed dd copy 1:1 to restore data - vxfs partition "/dev/vg01/lvol1" mounted as "/data" and some raw devs. After reboot system wrote this error: "vxfs mount: V-3-21268: /dev/vg01/lvol1 is corrupted. needs checking". So I wanted to run
fsck command to fix filesystem, logged as root, but to my surprise nothing happened. No error, no output, no result. Just like if it wouldn't run. I'm sure I was able to run
fsck many times before and I tried many variants of parameters, no deal. Any suggestions how to fix FS without using fsck? Or better, how to repair fsck to run properly? Thanks for every advice.
Ondrej Ilek.

Hello.
I have created a FS /u00/ and created a non-root login under this FS. Also, disabled direct root login. Now is it possible or worth moving this login over to the root partition or allowing mount/umount + fsck from a standard account. As I am not able to run fsck for this FS.

FSTAB(5) File Formats Manual FSTAB(5)
NAME
fstab, mtab - list of file systems to mount, mounted file system table.
SYNOPSIS
/etc/fstab
/etc/mtab
DESCRIPTION
/etc/fstab is a table of file system to mount at boot time, /etc/mtab is a table of currently mounted file systems as maintained by mount
and umount.
/etc/fstab is not read by mount as it should be. It is instead a simple shell script listing the three devices that Minix needs to oper-
ate: The device names of the root file system, the temporary (scratch) file system, and the file system for /usr. Of these only the /usr
file system is mounted in /etc/rc, the scratch file system is there for the system administrator to test new kernels, or as a temporary
file system.
/etc/mtab contains lines of four fields. The layout is:
device directory type options
These fields may be explained as follows:
device
A block special device.
directory
Mount point.
type
Either 1, or 2, indicating a V1 or V2 file system.
options
Either ro, or rw, indicating a read-only or read-write mounted file system.
FILES
/etc/fstab Shell script naming three important file systems.
/etc/mtab List of mounted file systems.
SEE ALSO
printroot(8), mount(1), fsck(1), mkfs(1).
BUGS
/etc/fstab is a joke.
