Default Temporarily squelching multipathd errors

Greetings,

I perform SAN-based snapshots on OCFS2 and ext3 filesystems under
dm-multipath. Before I snapshot the filesystem, I unmount and delete
the previous night's snapshot LUNs. Doing so causes (correctly)
multipathd to output the following errors:

<snip>
...
Jul 14 03:16:02 ausracdbd01 multipathd: mpath19: remaining active paths:
7
Jul 14 03:16:02 ausracdbd01 multipathd: sdci: tur checker reports path
is down
Jul 14 03:16:02 ausracdbd01 kernel: device-mapper: multipath: Failing
path 69:80.
Jul 14 03:16:02 ausracdbd01 multipathd: sdco: tur checker reports path
is down
....
</snip>

During this snapshot time, I would like to temporarily turn off the
verbosity of multipathd. Is this possible? It's mostly an annoyance
factor for me because our nightly centralized syslog scan picks up words
like 'fail' and generates a report to the system administrators (which
we then have to ignore for these messages).

TIA,

Daniel

Why not just remove the multipath from the multipathd topology before deleting the snapvol ?

multipathd -k"del map mpath19"

Default Temporarily squelching multipathd errors

When adding or removing LUNs, I always get multiple multipath messages
reporting that a path is down, sometimes even to devices that I have not
removed. I've tried removing all the SCSI devices (via "echo 1
>/sys/bus/devices/$DEVICE/delete"), flushing the multipath maps,
removing the mpath in question (via "multipathd -k"dep map $mpath"),
prior to unpresenting the LUN or doing a SCSI rescan when presenting a
LUN, all to no avail.

What is proper procedure to completely remove all SCSI devices and
multipath maps so that multipathd will not generate error messages when
the LUN is unpresented from the system?

TIA,

Daniel

This is my recipe:

- Take a note of "multipath -ll" output (SCSI-IDs, long multipath
identifiers, etc)
- Umount filesystem
- Deactivate VG
vgchange -an vg_XXX
- Export VG
vgexport vg_XXX
- Remove multipath
multipath -f <long-multipath-identifier>
- Unpresent/destroy array LUN
- Remove SCSI devices
echo 1 > /sys/bus/scsi/drivers/sd/<SCSI-ID>/delete
... (for all paths)
- Edit fstab

Default Temporarily squelching multipathd errors

I am still getting multipath errors when unpresenting and presenting
LUNs. I've traced it down to getting path failures everytime I either
remove or add a LUN to the system. The strange thing is that I get path
errors for maps that aren't related to the LUNs I am deleting or adding.
In this case, I am deleting the LUN with the map 'mpath18,' but other
maps complain whenever the LUN is deleted:

Nov 21 13:47:05 ausracdbd01 multipathd: checker failed path 67:208 in
map orabackup_hs
Nov 21 13:47:05 ausracdbd01 kernel: device-mapper: multipath: Failing
path 67:208.
Nov 21 13:47:08 ausracdbd01 multipathd: checker failed path 70:160 in
map mpath18

orabackup_hs

path 65:224.
Nov 21 13:47:10 ausracdbd01 multipathd: checker failed path 65:240 in
map limsd_arch


Sometimes I only get 5-10 "checker failed path" errors, other times I
get 30+.

Can anyone give me any advice? These are OCFS2 filesystems on RHEL5
attached to a HP EVA8000.

[root@ausracdbd01 ~]# rpm -qa | grep mapper
device-mapper-1.02.20-1.el5
device-mapper-1.02.20-1.el5

Relevant /etc/multipath.conf entries:
### HP Storageworks Arrays.

}



TIA,

Can you attach the 'multipath -ll' output? Run the program before
you delete/add the LUNs and after, please.

How do you delete/add the LUNs? Are you re-using the LUN number, or are you
actually deleting a LUN, deleting the block device as well, and then
when adding (with a new LUN number higher than the deleted one), rescanning
the SCSI host channel to get the new block device for the LUN?

Default Temporarily squelching multipathd errors

Right now I'm deleting the LUN, immediately creating a new LUN, and
presenting it back to the system with the same SCSI ID. Since it's a
snapshot, the LUN geometry is always the same. I've tried unpresenting
the LUN, deleting the SCSI devices, recreating/presenting the LUN, and
then doing a SCSI rescan, but the multipath errors are always there.

Here's the multipath listings. I am only deleting/presenting the
"mpath33" map, but you can see the multipath errors and the other paths
having a fault:

Unmounting /dev/mapper/mpath33p1...
Multipath listing before LUN is deleted...

How are you 'deleting' the mpath33 map? Are you using 'dmsetup remove mpath33'
?

I am not seeing how you are deleting the SCSI device of the node.
Are you doing 'echo 1 > /sys/block/sdab/device/delete' for all
of those block-devices that match the 'deleted LUN'?

How are you doing a SCSI rescan?

No, I am telling the storage unit to delete the LUN. In this test, I:

A) Unmount the filesystem
B) Tell the storage system to delete the LUN (which unpresents it,
obviously)
C) Tell the storage system to make a new LUN using the same WWID and
SCSI ID as before
D) Present the LUN

Since all this takes around 20 seconds, I can immediately mount the LUN
again on the server.

No, I am not. I have before, but it didn't seem to help.

I'm not in this test. Since all this takes around 20 seconds, I can
immediately mount the LUN again on the server with any SCSI devices
permanently disappearing.

Would you like me to:

A) Umount the filesystem
B) Perform a 'dmsetup remove mpath33'
C) Delete all SCSI devices via /sys/block/$device/delete
D) Tell the storage unit to unpresent and delete the LUN
E) Optionally do a SCSI rescan to clear everything out
F) Tell the storage unit to create the LUN with the same WWID and SCSI
ID
G) Perform a SCSI rescan
H) Do a multipath -v3 to get the maps back (?)
I) Fsck and mount the filesystem?

I believe I get the same results as what I pasted, but will prove it if
need be.

BTW, I do a SCSI rescan with the HP Fibreutils package (hp_rescan -a),
which basically does a "echo "- - -" >
/sys/class/scsi_host/${INST}/scan" and removes devices with "echo "scsi
remove-single-device $INST 0 $j $k" > /proc/scsi/scsi"

Thanks,

Daniel

Please do. Step B might be unnecessary as multipathd will figure out that
devices are gone (by step C) and start removing the block devices from the
map.

You only need to do the first step: echo "- - -" > /sys/class/scsi/host/hostX/scan
