Hi, by using mkfs.ext4 -E packed_meta_blocks=1 all the fs metadata is placed at the start of the disk. Unfortunately I have not found a way to enlarge the fs and maintain this property, new metadata is allocated from the added space. My attempts to work around the issue have failed: - adding resize=4290772992 in mkfs doesn't help - creating a bigger fs with packed_meta_blocks, then shrinking it, then re-extending it to the original size still allocates from the new space Is there a way to have metadata at the beginning of the disk and be able to enlarge the fs later? Planning to do this on big filesystems, placing the initial part on SSD extents; reformat+copy is not an option. This mailing list appears the best place to ask, sorry if this is considered off topic. Thanks. -- Roberto Ragusa mail at robertoragusa.it
