This one fails: mke2fs -j -b 4096 /dev/<3GB-blockdev> 32768 (mount + ext2online or resize2fs) kernel: JBD: resize2fs wants too many credits (1034 > 1024) Add one block to the initial mke2fs (32768+1 == 32769) and the problem is gone. Without the -b 4096 there's another resize problem mke2fs -j /dev/loop1 2048 mount /dev/loop1 /1 resize2fs /dev/loop1 says: resize2fs 1.40-WIP (14-Nov-2006) Filesystem at /dev/loop1 is mounted on /1; on-line resizing required old desc_blocks = 1, new_desc_blocks = 12 Performing an on-line resize of /dev/loop1 to 3072000 (1k) blocks. resize2fs: Invalid argument While trying to add group #256 and the kernel says: May 7 15:36:08 lokka EXT3-fs warning (device loop1): verify_reserved_gdb: May 7 15:36:08 lokka reserved GDT 10 missing grp 1 (8202) May 7 15:36:08 lokka After that, the filesystem has been resized to 2GB. I recall a 2G (?) limit for ext3 resizing with 1k blocksize but trying the above with 4096 1k blocks seems to work. fsck says it's ok all the time. -- Frank - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
