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

DEV: Size: 6103514112 (0x16bcc3c00)
The file system grew by 4768368MB.
