Error 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.

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
