Hi,
I’m starting to use stonith levels.
My existing (1-level stonith config) looks like this:
# pcs stonith config
Resource: fence_pm (class=stonith type=fence_powerman)
Attributes: fence_pm-instance_attributes
ipaddr=localhost
ipport=10101
pcmk_delay_base=60s
pcmk_delay_max=90s
pcmk_host_check=static-list
pcmk_host_list=gopher1,gopher2,gopher3,gopher4,gopher5,gopher6,gopher7,gopher8,gopher9,gopher10
Operations:
monitor: fence_pm-monitor-interval-60s
interval=60s
And I want to switch to a 2-level stonith config. I’d expected these commands
to work:
lustre_servers=gopher1,gopher2,gopher3,gopher4,gopher5,gopher6,gopher7,gopher8,gopher9,gopher10
# set up new fence agent
pcs stonith create fence_kdump fence_kdump pcmk_host_check=static-list
pcmk_host_list=${lustre_servers}
# set levels (priority) so pacemaker knows which to use first
pcs stonith level add 1 ${lustre_servers} fence_kdump
pcs stonith level add 2 ${lustre_servers} fence_pm
# verify config
pcs stonith level verify
The “pcs stonith create” succeeds, but the “pcs stonith level add” fails.
Looking at the man page, it looks like a comma-separated target list isn’t
allowed for “pcs stonith level add”. Is that correct?
In the man page, I see
Target may be a node name <node_name> or %<node_name> or
node%<node_name>, a node name regular expression regexp%<node_pattern>
or a node attribute value attrib%<name>=<value>.
Is “%” literal, here?
Do
“pcs stonith level add <level> node%<node_name> <stonith_id>” and
“pcs stonith level add <level> %<node_name> <stonith_id>” and
“pcs stonith level add <level> <node_name> <stonith_id>” mean something
different? They seem identical from brief experiments.
How is “attrib%<name>=<value>” used?
Thanks,
Olaf
