Hi,
The re-verification of this shows it's indeed fixed with multipath-tools
0.4.9-3ubuntu7.4.
Details provided.
Software version check:
# lsb_release -d
Description: Ubuntu 14.04.3 LTS
# dpkg -s multipath-tools | grep ^Version:
Version: 0.4.9-3ubuntu7.4
Set known values to the fast_io_fail_tmo (21) and dev_loss_tmo (42) files,
and activate multipathd to re-set the values according to its configuration.
# /etc/init.d/multipath-tools stop
* Stopping multipath daemon multipathd
...done.
# for fastiofail in
/sys/class/fc_remote_ports/rport-*/fast_io_fail_tmo; do echo 21 > $fastiofail;
done
# grep -h . /sys/class/fc_remote_ports/rport-*/fast_io_fail_tmo | sort
-u
21
# for devloss in /sys/class/fc_remote_ports/rport-*/dev_loss_tmo; do
echo 42 > $devloss; done
# grep -h . /sys/class/fc_remote_ports/rport-*/dev_loss_tmo | sort -u
42
# /etc/init.d/multipath-tools start
* Starting multipath daemon multipathd
...done.
The storage products used:
# multipath -l | grep ^mpath | cut -d, -f2 | sort -u
2107900
2145
2810XIV
FlashSystem-9840
The active configuration for them:
# multipathd -k'show config' | grep '{\|}\|product\|tmo'
defaults {
fast_io_fail_tmo 10
}
...
devices {
...
device {
product "2107900"
}
device {
product "2145"
dev_loss_tmo 120
}
...
device {
product "2810XIV"
}
device {
product "FlashSystem-9840"
fast_io_fail_tmo 25
dev_loss_tmo 300
}
}
...
The active configuration is sysfs:
The sysfs setting (see below) are all set correctly,
according to the multipath configuration (above).
On rports to 2107900 or 2810XIV, devloss = 42 (not specified; system)
and fastiofail = 10 (defaults).
On rports to 2145, devloss = 120 (device), fastiofail = 10 (defaults).
On rports to 9840, devloss = 300 (product) and fastiofail = 25
(product).
On rports not connected to any of those, the system/known values
are left unchanged.
