----- Original Message ----- | Hello, | I have a Centos 6.2 clsuter with a CLVM partition on which I have a | GFS2 | file system. | The problem rises when I make a snapshot from my FC NetAPP FAS2020. | After I make the snapshot (it is a rw snapshot) of my LUN, I am not | able | to mount it from any of my cluster nodes, | because the Physical Volume is seen two times one time on the | standard | LVM partition | and the other time on the snapshot partition so te PV is foudn to be | duplicate and I cannot mount it. | | > pvs | Found duplicate PV 5ZTDCmWHDH6M04nl58Wyyi3nYG8BOCRo: using | /dev/mapper/mpathl not /dev/mapper/mpathi | PV VG Fmt Attr PSize PFree | /dev/mapper/mpathk NetCluster0 lvm2 a-- 1.67t 1020.00m | | | I need a hint on how to fix this problem. I need to access the | snaphot | volume to backup my data but I am unable to do it... | | thank you very much HINT: You'll need to generate a new UUID/rename the PV. (pvchange -u) -- James A.
