Chkfsys

On one of our computers running QNX 4.25, following has been observed…

#chkfsys -vuP /dev/hd0t77 shows following result

Inode block 0x1EFD7 is not in the /.inode file
action deferred until end of chkfsys
Paused … (on pressing ENTER,)

Inode block 0x… is not in the /.inode file
action deferred until end of chkfsys
Paused …



The above-mentioned message appears repeatedly. After hitting enter every
time for the Paused prompt, following message is displayed…

The /.inode file need to be rebuilt; This necessitates rebuilding the
bitmap. Write new bitmap ? Y

chkfsys : could not read ‘new inode’ extent block (0x404024)
Serious error : continue program ? Y
chkfsys : could not rebuild inode file

Serious error : continue program ? Y
chkfsys : could not rebuild inode file

//1/bin/chkfsys terminated (SIGSEGV) at 0007:0002728C
%1 195 Memory Fault chkfsys -vuP /dev/hd0t77

What does such a message mean? Is our hard disk damaged? or Is QNX file
system damaged? ‘dcheck’ reports no errors…All of our sorce code files
and data are intact.

Thanks,
Krupa

This is the first time I ever see checksys report an error about inode
block.

That data corruption is so bad that chkfsys crashed on it.

Is our hard disk damaged? or Is QNX file
system damaged? ‘dcheck’ reports no errors…

dcheck only run one test per block, it may not detect transiant problems.
Personally I would try with another HD, it definitely smells bad.

All of our sorce code files and data are intact.

Then make a backup ASAP…
