| Habib-A | helllo all im looking for help regarding a cinder lvm backend issue | 10:33 |
|---|---|---|
| Habib-A | i want to mount a cinder volume directly to cinder and access its data | 10:35 |
| Habib-A | when i try to mount volume it says unknown file system | 10:35 |
| Habib-A | if i try to mount it using the iscasi initiator (iscasiadm) i always get failed auth even though i added the server to acls and have same user/pass on both sides | 10:36 |
| Habib-A | can anybody see my msgs ?! | 10:36 |
| auniyal | hey Habib-A can you share cmds you tried and errors | 10:52 |
| Habib-A | hey auniyal here is the cmds : mount /dev/mapper/cinder--volumes-volume--101bbe3f--1e3e--4b24--bb7d--9dba2b3b50f9 /mnt | 12:03 |
| Habib-A | mount -t ext4 /dev/mapper/cinder--volumes-volume--101bbe3f--1e3e--4b24--bb7d--9dba2b3b50f9 /mnt | 12:04 |
| Habib-A | mount: wrong fs type, bad option, bad superblock on /dev/mapper/cinder--volumes-volume--101bbe3f--1e3e--4b24--bb7d--9dba2b3b50f9, | 12:04 |
| Habib-A | missing codepage or helper program, or other error | 12:04 |
| Habib-A | In some cases useful info is found in syslog - try | 12:04 |
| Habib-A | dmesg | tail or so. | 12:04 |
| Habib-A | and here is the iscsi error " iscsiadm --mode node --targetname iqn.2010-10.org.openstack:volume-02a36849-3599-4474-9bb1-3cfdc3fa40b2 --portal 10.X.X.X --login | 12:06 |
| Habib-A | Logging in to [iface: default, target: iqn.2010-10.org.openstack:volume-02a36849-3599-4474-9bb1-3cfdc3fa40b2, portal: 10.X.X.X,3260] (multiple) | 12:06 |
| Habib-A | iscsiadm: Could not login to [iface: default, target: iqn.2010-10.org.openstack:volume-02a36849-3599-4474-9bb1-3cfdc3fa40b2, portal: 10.X.X.X,3260]. | 12:06 |
| Habib-A | iscsiadm: initiator reported error (24 - iSCSI login failed due to authorization failure) | 12:06 |
| Habib-A | iscsiadm: Could not log into all portals | 12:06 |
| auniyal | so reason of asking for cmds is, I don't think we need to run mount cmd manually, Cinder should be able to do that. I was looking for docs for same but could not find them. | 12:26 |
| auniyal | can you tell more about your setup, | 12:26 |
| auniyal | how many nodes you have and in which node you are mounting, | 12:27 |
| auniyal | how did you create cinder--volumes-volume--101bbe3f--1e3e--4b24--bb7d--9dba2b3b50f9 | 12:27 |
| auniyal | I believe once these are clear someone from storage here might add/suggest more points | 12:29 |
| Habib-A | ok what i have is a production environment using a single node of cinder with lvm backend problem is i had i vm with important data corroupted and i need to retrive data from it so i had a backup of the cinder node i resorted it without networking and now i want to mound the failing vm volume directly to cinder to recover data i tried direct mount and iscasi mount and both had issues as stated above | 13:00 |
