Hello,
I have a storage server running Debian 7.6 x64. It's an HP server with 24
HDDs and a hardware RAID controller. It has a 2.9 TB ext4 filesystem which
resides on a RAID 5 volume, and I recently needed to grow this filesystem
so I added more disks to the volume and then used parted to grow the
partition to the new size of 5 TB, so the space is now available in that
partition:
# parted print /dev/sdb
Model: HP LOGICAL VOLUME (scsi)
Disk /dev/sdb: 5001GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 1049kB 5001GB 5001GB ext4 primary
However, the filesystem is still stuck at the old size:
# df -h /dev/sdb1
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 2.7T 2.5T 104G 97% /export
I cannot figure out how to resize the actual ext4 filesystem to use the
added space. I have tried both resize2fs without any luck. When I try
resize2fs, I get this error:
# resize2fs /dev/sdb1
resize2fs 1.42.5 (29-Jul-2012)
resize2fs: /dev/sdb1: The combination of flex_bg and
!resize_inode features is not supported by resize2fs.
In a potentially stupid move, I did indeed remove the resize_inode feature
from this filesystem in order to get parted to work with it, which
ultimately proved unnecessary, but now I cannot add it back:
# tune2fs -O resize_inode /dev/sdb1
tune2fs 1.42.5 (29-Jul-2012)
Setting filesystem feature 'resize_inode' not supported.
Is there a way I can resize this filesystem to use the additional 2 TB
available to it? The output of dumpe2fs is below (not including the data
about the 22,355 groups in the filesystem):
