Description adler 2000-11-16 20:29:49 UTC

I've created a 280Gigabyte file system over 4
70 Gig partitions using a raid0 file system.
When I started using the file system, I started
getting the following errors in my /var/log/messages
file.

ext2_new_block: Free blocks count corrupted for block group 1838

Nov 16 15:11:14 dmz0 kernel: EXT2-fs error (device md(9,0)):

I'm worried that the file system is not working properly. I'll
be glad to run any tests you wish to further constrain the
problem.

Does this still show on 2.2.19 kernels ?

Comment 2 adler 2001-06-05 10:28:57 UTC

Sorry, your too late for this. Because of this bug, I swapped out
the alpha mother board for an intel one, and I'm now running SGI's
redhat 7.1 with xfs. the 280Gig file system is an XFS one and
seems to be running fine. I guess you should close this one since
I will not be able to reproduce errors for you.
