[ovirt-users] Very big device. Trying to use READ CAPACITY

hi. i'm using ovirt version 4.0 . I've created two LUNs. firs lun is 2047GB and working properly as data domain. but when i try to add second lun as second data domain, i get this error on server: Jun 21 13:22:41 compute52 kernel: sd 12:0:0:16384: [sdf] Very big device. Trying to use READ CAPACITY(16). Jun 21 13:22:41 compute52 kernel: sd 5:0:0:0: [sdb] Very big device. Trying to use READ CAPACITY(16).

BTW: is there any good documentation for ovirt and FC in detail. all administration docs are using GUI ... . -- R&D expert at Ferdowsi University of Mashhad https://ir.linkedin.com/in/imandarabi <https://www.linkedin.com/profile/public-profile-settings?trk=prof-edit-ed...
