Hallo All,

HP-UX 11.0 if message

Hi,

Basically what had happenned is that the HFS subsystem allocated a free inode structure but only to find that this inode is not free since i_mode is still set!

Now to find out which inode and which HW causes this we need to have a look in the Oldsyslog file on the system for more info.

Please check this an post the complete message.

Thank You for Your help and
whole message from OLDsyslog
is following:
vmunix: mode = 040770, inum = 4331162, fs = /t5, ip = 0x01a4d990

It seems as file system
"/t5" - but what would be
happend when file system
"/t5" is on disc array RAID 5
and this seems good ?

Thank You

Hi,

Yes it is /t5 filesystem.
You could check with fsck to see it gives some error's.
Could be a hw error, mirror error, fs corruption, file system could have been full.

Try locating the referenced inode

vmunix: mode = 040770, inum = 4331162, fs = /t5, ip = 0x01a4d990 #

find /t5 | xargs ls -li {} \; | grep 4331162
