Re: [ovirt-users] vdsm lvm filter
I've got a setup with with ovirt and an equallogic iscsi. Im
using the dell
hit drivers. Install all good, after a reboot the storage won't come up.
From the vdsm logs i can see the volume groups can't be found. in the lvm
vgs command the following filter is used: [ '\''r|.*|'\'' ] .
If I change the LVMCONF_TEMPLATE in /usr/share/vdsm/storage/lvm.py and add
the filter [ "a|^/dev/eql/ovirt.*|" ], the volume group is found and storage
will be attached.
How is the lvm filter constructed? And how can i make sure my volume groups
are found without editing /usr/share/vdsm/storage/lvm.py?
A shoot from darkness...:
134 USER_DEV_LIST = filter(None, config.get("irs",
"lvm_dev_whitelist").split(","))
135
136
137 def _buildFilter(devices):
138 strippeds = set(d.strip() for d in devices)
139 strippeds.discard('') # Who has put a blank here?
140 strippeds = sorted(strippeds)
141 dmPaths = [dev.replace(r'\x', r'\\x') for dev in strippeds]
142 filt = '|'.join(dmPaths)
143 if len(filt) > 0:
144 filt = "'a|" + filt + "|', "
145
146 filt = "filter = [ " + filt + "'r|.*|' ]"
147 return filt
148
149
150 def _buildConfig(devList):
151 flt = _buildFilter(chain(devList, USER_DEV_LIST))
152 conf = LVMCONF_TEMPLATE % flt
153 return conf.replace("\n", " ")
So maybe lvm_dev_whitelist option in vdsm.conf ?
