hi, The shared that i have is raid5, and i have completedthe partitions i want and i formated them as gfs and mount them and everything is OK. but now , i want to setup rawdevices, and i want to put each rawdevice in one partion , so i have taken the free space from the shared and made it an lvm partition, and then i partioned the new lvm partition into 19 partitions : /dev/vg0/r1........ /dev/vg0/r18 and i want to format them as gfs filesystem i used the same procedure used from the beggining so i made another partition named as /dev/vg0/newgfs (to use as CCS file) but when i make : pool_tool -c to any of the new partitions it says that ( Unable to open device "/dev/lvm(a-s)" then it writes pool label written successfully from the file. when i run pool_tool -s it writes an <ERROR> with the new partitions. This is the problem. ????? Thanks
