how to copy data from crashed disk
after system (or disk) crash i cannot mount /dev/vg01/faktury. I started fsck -ofull, but it is working 2 days without result (still in pass1). Is there other way to copy data from this volumin to other disk?
My system HP-UX B.11.00, volumin size 8GB.

Re: how to copy data from crashed disk
if the system can not mount the disk, it can not see that data on the disk.
So either you somehow get the system to mount the disk and copy with dd or you try to sector copy the disk via a third-party recovery tool. Either way you will probably loose data and should restore from backup!!

Re: how to copy data from crashed disk
If you are unable to mount the file system, i am afraid you would not be able to recover the disk contents yourself. You may have to settle for any of the following depending on how important the data is for your organization
1. Use some DATA RECOVERY TOOL
2. Seek some DATA RECOVERY COMPANIES services
3. Use the last backup to restore the data
If you don't have a valid backup, then you are left with only 2 choices really.
All the best

Re: how to copy data from crashed disk
Did you try to boot from cdrom already?
When booted from cdrom you can mount each lvol
at a time to a temporary mount point and try to recover what ever is left to another lvol.
But if there is a hardware failure then this option won't work.
Regards,
Bob

Re: how to copy data from crashed disk
If you absolutely must have this data (ie, no backups) then contact a data recovery company. Be prepared to spend thousands of dollars as the task to recover the data can be extremely labor- and equipment-intensive.

Re: how to copy data from crashed disk
if the system doesn't mount without fsck, you can try to mount it with the option -f (for force).
Sometimes it works.
Then you could copy datas from this disc.
