| Hi, We are running Cenos5.5 (gfs2-utils.x86_64 v0.1.62-20.el5) cluster. We want to add another 5T disk space on the filesystem - expand from 19T to 25T, however it doesn't grow over 20T. There was no error when I did test run. So just wondering if there is a limitation of gfs2_grow which only can grow gfs2 filesystem upto 20T ? Is there anyone had same experience? Test run # gfs2_grow -T /mnt/fsbackup (Test mode--File system will not be changed) FS: Mount Point: /mnt/fsbackup FS: Device: /dev/mapper/fsbackup-fsbackup01 FS: Size: 4882811901 (0x12309cbfd) FS: RG size: 524244 (0x7ffd4) DEV: Size: 6103514112 (0x16bcc3c00) The file system grew by 4768368MB. gfs2_grow complete. Actual run # gfs2_grow /mnt/fsbackup FS: Mount Point: /mnt/fsbackup FS: Device: /dev/mapper/fsbackup-fsbackup01 FS: Size: 4882811901 (0x12309cbfd) FS: RG size: 524244 (0x7ffd4) DEV: Size: 6103514112 (0x16bcc3c00) The file system grew by 4768368MB.
