similar to: [PATCH] mke2fs: Use e4fsprogs programs if available.

I've been thinking recently that we should re-enable DIR_INDEX in mke2fs by default. When it first came out, we had done this and were bitten by a few bugs in the code. However, this code has been in heavy use for several thousand filesystem years in Lustre, if not elsewhere, and I'm inclined to think it is pretty safe these days. Likewise, RHEL/FC have had RESIZE_INODE as a standard

The changes since the previous patch: - safe ADD_ARG macro for adding arguments to a fixed size stack array - support for testing functions that return RHashtable, ie. tune2fs-l. - add tests that set (tune2fs) and get (tune2fs-l) various parameters. - only one 'intervalbetweenchecks' parameter (in seconds) Rich.

I know there is no straightforward way to recover deleted files on an ext3 file system, but is there any way to recover from an accidental mke2fs? -- --------------------------------------------------------------- Paul Raines email: raines@nmr.mgh.harvard.edu MGH/MIT/HMS Athinoula A.

Hi all, are there any plans that future versions of mkfs.btrfs will do an initial pre-discard for SSDs? (AFAIK mkfs.btrfs does not do this currently) For Ext4, mke2fs does this with the -E discard option. From the mke2fs manpage: -E discard Attempt to discard blocks at mkfs time (discarding blocks initially is useful on solid state devices and sparse / thin-provisioned storage). When

Hi, I have a doubt if I use the mke2fs option the right way. I formatted two different disks, one with $ mke2fs -b 4096 -E stride=16 -m 1 -T news /dev/sdd and the other with $ mke2fs -b 4096 -E stride=16 -m 1 -T largefile4 /dev/sde sdd is supposed to get files between 8k and 16k. sde will handle files with a fixed size of 32Mb. Then I tried this : $ dd if=/dev/zero of=/mount-sdx/file bs=4k

My wipefs has no --force option, as a result mke2fs command in guestfish fails. Looks like 72dd398679cd0bb803daf306d12558369615ba70 needs an adjustment to make use of do_wipefs? Also str_wipefs is not used in that file. Olaf

Tried to make it in accordance with your comments. Difference to v1: Added reply_with_error where necessary. Changed name get_min_size -> vfs_min_size. Difference to v2: Changed name to vfs_minimum_size. Changed parsing to xstrtol + STR* macros where possible. Difference to v3: Decapitalize error messages.

I am trying to get a 9550SX to support a 1.5TB raid partition. I am unsure whether this is a driver problem, or an ext3 problem (as am getting some other wierdness detecting LUNs), but... fdisk recognizes the disk OK. I make a single extended partition with a single 1.5TB logical partition inside it. I then run mke2fs -j /dev/sdb It gets to writing inode tables, and wants to write 11176 block

So I have been playing with a RAID 10 f2 ( 2 disks far layout) setup...thanks for all of the advice..Now I am playing with the format and want to make sure I have it setup the best that I can, my raid was built using the raid 10 option with 2 disks with the layout=far, chunk size 512....now I read all of the docs I could find about format and stride and stripe size and this is what i came up

This is a simpler patch that removes GUESTFSD_EXT_CMD completely.

Hi, Is mke2fs' stride option relevant for a multi-striped LVM volume? Cheers, Stephen
