Hi,
on Ubuntu server 12.04 (3.2.0-24-generic) I use open-iscsi (2.0-871),
multipath-tools (v0.4.9) and ocfs2 (1.6.3-4ubuntu1) to access shared
storage HP P2000 G3 iscsi. Even short network connectivity loss is causing
immediate server crash and reboot. In syslog I can not found any clue what
might hapened.
Configuration:
iscsid.conf
Code:
node.conn[0].startup = automatic
node.startup = automatic
node.session.timeo.replacement_timeout = 180
node.conn[0].timeo.login_timeout = 15
node.conn[0].timeo.logout_timeout = 15
node.conn[0].timeo.noop_out_interval = 5
node.conn[0].timeo.noop_out_timeout = 5
node.session.err_timeo.abort_timeout = 15
node.session.err_timeo.lu_reset_timeout = 30
node.session.initial_login_retry_max = 4
node.session.cmds_max = 128
node.session.queue_depth = 32
node.session.xmit_thread_priority = -20
node.session.iscsi.InitialR2T = No
node.session.iscsi.ImmediateData = Yes
node.session.iscsi.FirstBurstLength = 262144
node.session.iscsi.MaxBurstLength = 16776192
node.conn[0].iscsi.MaxRecvDataSegmentLength = 262144
discovery.sendtargets.iscsi.MaxRecvDataSegmentLength = 32768
node.session.iscsi.FastAbort = No

ip_address = 192.168.1.11
ip_port = 7777
node:

cluster = ocfs2
number = 1
ip_address = 192.168.1.12

How can I troubleshoot this issue?
Thanks for any help.
