needs help, root inode gone after usb bus reset on sata disks
Hello everybody, I am new to this list, so welcome everybody. Last 2 week I had two harddisk crashes with my ext2 file system. This is what sort of happed with both of the disk: I pluged in my USB to SATA converter in my harddisk that has an ext2 filesystem. I mounted the partition, went to a directory that had a DVD image. I mounted the dvd image in the same directory and started watching the

Journal size
Is there any way to query the size of an existing journal? I have heard a number of sizes thrown around as defaults, but I need to be able to reliably get the exact journal size.

SCSI bad block table display
Hi All: Is there a utility available that will allow for the dump/display of the bad track table of a SCSI drive. We had this capability on SCO OSR5 but I have not been able to locate anything similar for Linux. The closest I have found is the badblocks utility that is part of the e2fsprogs package but this appears to only test for bad blocks not display the current bad block table contents.

More external journal woes.
I have been playing with external journals some more and thought I should share some experiences. I am running 2.4.16 with the ext3 patches from Andrew Morton and e2fsprogs 1.25 I have an ext3fs filesystem on an 8 drive RAID5 array and place the journal on a partition of the mirrored pair that I boot off (all drives SCSI). I have tried pulling the power cable and seeing what happens. I finally

root fs not mounting ext3
I am using SuSE 7.3 compiled ext3 support into the kernel and installed it. All my partitions load up as ext3 except / . I ran tune2fs several times, still doesn''t take on the / drive. Most recent dumpe2fs -h show no features on that drive=, I keep going around in circles, removing .journal from / and running tune2fs but it never works for / What am I doing wrong?

ext3 compatibility between 2.4 and 2.6 kernels
Hello-- We have a system where a central server formats removable hard disks, which are then booted in an embedded system running a highly modified RH9. The removable disks themselves contain boot, root, and data filesystems. The problem we''ve encountered after upgrading to FC3 / kernel 2.6 on the central server is that the 2.4 kernel in the embedded system cannot read the root

New user''s naive question
I have installed Mandrake 8.1 and chose ext3 for my main partitions (other than root). However, stupidly, I cannot now remember whether I specified ext3 for some other partitions that I haven''t yet mounted (these are essentially just spare capacity, though they may have some files on them if they weren''t formatted). Is there a simple way of telling whether I should mount

clone RHEL 4 ext3 partition
Hi, I''m about to roll out a whole bunch of Redhat Enterprise 4 workstations and have run into problems cloning from the original. Normally I would use ghost (v7.5) because it does a nice job when cloning to a different sized disk.Unfortunately it comes up with read error 29004. Looking around it seems that Symantec don''t support Fedora Core 3 (with Ghost v.8 - don''t

e2fsprogs Help.
...out e2fsprogs. I am very new to the kernel as well as file system programming. My task is to collect superblock, inode, bitmap ( or free list) information from ext2/ext3 filesysteam. After searching the google, I came to know about e2fsprogs, which I was able to install and use at least "dumpe2fs" utility. This utility do not provide timestamp of each allocated inode and I am thinking of modifying source code of e2fsprogs. My two questions are: 1. Is it correct to use "dumpe2fs" program and modify for timestamp ? 2. I could not understand the main purpose of e2fsprogs....

botched RAID, now e2fsck or what?
Hi all, Somehow I managed to mess with a RAID array containing an ext3 partition. Parenthesis, if it matters: I disconnected physically a drive while the array was online. Next thing, I lost the right order of the drives in the array. While trying to re-create it, I overwrote the raid superblocks. Luckily, the array was RAID5 degraded, so whenever I re-created it, it didn''t go into

"ext2fs_check_if_mount: No such file or directory while determining whether" messages
Hi. I was using 2.4.10 with ext3 0.9.10 and thought it was time to use -ac for the first time because 2.4.12-ac3 includes 0.9.12. I don''t know what I did to get the following messages, but in my last boot I removed /etc/mtab (at runtime) and made it a symlink to /proc/mounts. Not sure if a bad idea, but the only problem until I rebooted was the need of losetup -d. When I

ext4 and extremely slow filesystem traversal
Hello list, I have troubles with the daily backup of a modest filesystem which tends to take more that 10 hours. I have ext4 all over the place on ~200 servers and never ran into such a problem. The filesystem capacity is 300 GB (19,6M inodes) with 196 GB (9,3M inodes) used. It''s mounted ''defaults,noatime''. It sits on a hardware RAID array thru plain LVM slices.

maximum MDT inode count
...ence that have 2B or more total inodes? This is fairly unlikely, because it would require an MDT filesystem that is > 8TB in size (which isn''t even supported yet) and/or has been formatted with specific options to increase the total number of inodes. This can be checked with "dumpe2fs -h /dev/{mdtdev} | grep ''Inode count''" on the MDT. If there are issues with privacy, please email me directly. Otherwise, I think people would be interested to know what the larger MDT sizes are (even if they aren''t as high as 2B inodes). Cheers, Andrea...

mount /dev/hda6 ext3
Dear all, I followed the instructions found on http://www.zip.com.au/~akpm/linux/ext3/ext3-usage.html to convert / on several of my boxes to ext3. Strange to me, on some boxes it perfectly worked while on others it didn''t. One of the differences found is that on the ok-boxes mount reports: /dev/hda3 on / type ext3 (rw,errors=remount-ro) /*
