I created a filesystem as follows: mke2fs -j -O dir_index -O sparse_super -T largefile /dev/drbd/6 Here's the the output from df Filesystem Size Used Avail Use% /dev/drbd/6 475G 33M 452G 1% It seems that ext3 has taken 23 GB, which is about 5% of the total disk size, for itself. Is that right? If that is, indeed, the case, why does df just list 33M as being

Let me preface this by saying "Yes, I know *nix filesystems don't need to worry about fragmentation". That said, is there a way to check the overall level of fragmentation of a live ext3 filesystem? I know about filefrag, but that's for specific files. And I think e2fsck tells you, but only if you take the filesystem offline for the scan. Is there anything that will give

Someone recently posted the following statement midway down the page at http://forums.gentoo.org/viewtopic-t-305871-postdays-0-postorder-asc-highlight-ext3+ordered+data-start-25.html >You don't need to defragment ext2/ext3 because as you use the >filesystem file blocks and inodes are moved around and reallocated >to keep the data nearly contiguous.

Hi - We have had a raid failure, we have some what recovered but we continue to see the following ext3 message...

Hi, There wasn't much information regarding fragment support of ext2/3 since 2003 [1], Andreas stating that there were problems with the xattr implementation. Has this changed in the meanwhile? My second question is regarding the bytes-per-inode ratio: What benefits would I gain from having fewer inodes? I reckon it's only diskspace (if so, how much?). best regards, Michael Renner [1]

Hi All, Can anyone help me in resolving this problem. I use Redhat 9 Enterprise edition. I have a session in which I logged in as a root. When I issue the command "su" from any other user it is throwing error "su : Incorrect password", If I try to change the password from the root session, it is throwing error "passwd : module unknown".

Hi, After panic boot, I have executed fsck for the mount point and we couldn't find a single file. We have lot of directories under lost+found like this #3194985. Can anyone tell me how to recover the data from this folder? This is urgent. Thanks in advance for your help.

I just discovered two directories with the same number of files and the same number of hard links but different size: # stat /home/david/linuxburg/fax.old/docq_ps.nnnn \ /hdsync/home/david/linuxburg/fax.old/docq_ps.nnnn File: `/home/david/linuxburg/fax.old/docq_ps.nnnn' Size: 8192 Blocks: 16 IO Block: 4096 directory Device: 801h/2049d Inode: 52060

Are we likely to see patches to allow 16TB ext3 in the mainstream kernel any time soon? I am working with a storage box that has 16x750GB drives RAID5-ed together to create a potential 10.5TB of potential storage. But because ext3 is limited to 8TB I am forced to split into 2 smaller ext3 filesystems which is really cumbersome for my app. Any ideas anybody?

Hello, I have a 1.3TB ext3 filesystem that has been in service for about 3 months. About 6 days ago the Emulex fibrechannel controller logged a SCSI error and the filesystem changed to RO. It appears that the filesystem instantly changes to RO and prevents the journal from working, therefore invalidating the filesystem. The filesystem was unmounted and a remount was attempted. The mount failed

Hi, I connected my harddisk which had ext3 filesystem and some files archived in it as slave device and issued "mkfs /dev/hdb2" accidentally. Immediately I issued Ctrl C and stopped the process. But before that it had deleted some 100 Blocks. After that I am unable to boot that hard disk as primary device. The system is asking me "please insert a valid boot device and press

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.

I have an ext3 filesystem mounted r/w on 1 host and r/o on multiple hosts. Dangerous but cost effective. I recently implemented some protection through a fc switch that restricts some hosts to r/o access to the data luns. So if someone types mount -o rw or something, all is not lost. The issue occurs when it's mounted r/w on 1 host and another host attempts to mount it r/o. The mount

Hello, I looked through the archives a bit and could not find anything relevant, if you know otherwise please point me in the right direction. I have a ~3T ext3 filesystem on linux software raid that had been behaving corectly for sometime. Not to long ago it gave the following error after trying to mount it: mount: wrong fs type, bad option, bad superblock on /dev/md0, or too many

Hi, I am using kernel 2.6.15.4. On my system, I first created a partition with EXT3 and put some data on it. Later, I deleted the partition, and re-created another partition with the same starting block number and a higher ending block number. I intended to format it with another filesystem, but surprisingly (or maybe just to me), the superblock of the partition had not changed. I could still

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
