Mark,

No, it is not, but I can bring it up.

Thanks,
Hank

Hank,

Is the owning system up and running with this file system mounted?

Subject: I/O Error on Readonly Filesystem


Hello,

I am sharing the "/usr" (reiserfs) filesystem across several zVM Linux
Guests.  All Linuxes are SuSE 2.4.7.  I am seeing the following error
messages in "/var/log/messages":

Mar  4 07:36:02 wcs-mf-winxs-db2p kernel: end_request: I/O error, dev 5e:09

I interpret the 5e:09 as Major 94, Minor 9, which in my case is
"/dev/dasdc1".  The contents of "/proc/dev/dasd/devices" follows:

0200(FBA ) at ( 94:  0) is dasda:active at blocksize: 512, 262144 blocks,

The contents of "/etc/fstab" follows:

/dev/dasda1     swap                      swap            defaults   0   0
/dev/dasdb1     /                         reiserfs        defaults   1   1

The contents of "zipl.conf" follows:

parameters="dasd=0200,0201,0202(ro),0203-027F,0301-0303 root=/dev/dasdb1
noinitrd"


The VM directory MDISK entry for the owning user follows:

MDISK 202 3390 1426 1425 LN1516 RR ALL SOME FEW


The VM directory LINK entry for sharing users follows:

LINK SYSSOFT2  202 202 RR


I ran "fsck" on the filesystem, the output follows:

wcs-mf-winxs-db2p:~ # fsck /dev/dasdc1
Parallelizing fsck version 1.19a (13-Jul-2000)

<-------------reiserfsck, 2001------------->

Anyone have any ideas on how to resolve this?
