Hi Experts, I want to grow the ext4 file system on mounted device by running resize2fs utility but it fails, same works in case of unmounted FS with additional invocation of e2fsck utility. This is what i am doing 1)Rescanning the device echo "1" | sudo tee /sys/block/sdd/device/rescan 2) Extending the partition growpart /dev/sdd 1 3) resizing the file system resize2fs /dev/sdd1 resize2fs 1.43-WIP (20-Jun-2013) The filesystem is already 43253499 blocks long. Nothing to do! parted -s /dev/sdd1 print free Model: Unknown (unknown) Disk /dev/sdd1: 177GB Sector size (logical/physical): 512B/4096B Partition Table: loop Number Start End Size File system Flags 1 0.00B 177GB 177GB ext4 Any help? Thanks, Alok
