similar to: another seriously corrupt ext3 -- pesky journal

I am new to ext3 + external journal. Is there any howto I can look at? this is what I understand 1. mke2fs -O journal_dev /dev/md5 2. mke2fs -J device=/dev/md5 /dev/md0 3. mount /dev/md0 / -t ext3 ( hmm.. what do I need to put on fstab?? ) /dev/md5 is a two drive RAID 1 partition /dev/md0 is a 4 drive RAID 5 partition. questions: 1. I am running RedHat 9.0. what extra software I need to

After a (hardware) crash yesterday, I was unable to boot up due to unrecoverable ide errors (according to the printk()s) when accessing the root filesystem's journal for recovery. Unable to recover, I tried deleting the has_journal option, but that was disallowed given that the needs_recovery flag was set. I saw no way to unset that flag. Unable to access the backups (they were on a fw

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 made an ext3 filesystem with 8kB block size: # mkfs.ext3 -T largefile -v -b 8192 /dev/md0 Warning: blocksize 8192 not usable on most systems. mke2fs 1.38 (30-Jun-2005) Filesystem label= OS type: Linux Block size=8192 (log=3) Fragment size=8192 (log=3) 148480 inodes, 18940704 blocks 947035 blocks (5.00%) reserved for the super user First data block=0 290 block groups 65528 blocks per group,

Hello, I come to you beacause i have something that i dont understand : i m using udev on a debian sid with 2.6.15.1 kernel. I have created an deprecated raid at /dev/md0 when i tried doing mkfs.ext3 /dev/md0 i have got : mke2fs 1.39-WIP (29-Mar-2006) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 4643968 inodes, 9277344 blocks 463867 blocks (5.00%)

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

My UPS failed and my server took an 'unscheduled outage' a few weeks ago. The only casualty appears to be a volume I used for backup. I usually maintain data on multiple hard disks, but in this case I errantly had some data (of marginal value) on this file system. At this point, the data is not worth enough for me to send the drive out for data recovery, but it's worth enough to

I just came back after being out for the evening. Apparently there was a power failure long enough to discharge the UPS completely on my Linux box. After powering back up, I received notice that the / filesystem needed "manual fsck"ing. I booted off CD and attempted to fsck. Unfortunately, everything I've tried has proved futile and I'm _desperate_ for some help. I've

Hi, I've just recently noticed that the ext3 projects is being actiavely maintained (again?). And looking at the new pages for 2.4.x it really made me interested. But I've got a few small questions I'd like to clarify before I start to use it. 1) Tune2fs and mke2fs talk about a "default journal size" that is depending on the partition size but don't give

We are having problems remounting an ext3 filesystem using an external journal device. The filesystem in question was working fine until the server was rebooted. This is what we see on dmesg when trying to mount: EXT3: failed to claim external journal device. The external journal lives on a LVM2 logical volume and it seems to be accessible ( we can dumpe2fs and see filesystem information).

Hello Is it possible to externalize the journal of an already existing (journal inside) ext3 FS ? Here's what I did to create a new FS with external journal for /dev/emcpowerl2 on /dev/emcpowerl2 mke2fs -O journal_dev /dev/sda10 mke2fs -J device=/dev/sda10 /dev/emcpowerl2 it works perfectly , but can I do the same whitout reformating the original FS; /dev/emcpowerl1 which is in

Hello everyone. I'm trying to install CentOS 8 with root and swap partitions on software raid. The plan is: - create md0 raid level 1 with 2 hard drives: /dev/sda and /dev/sdb, using Linux Rscue CD, - install CentOS 8 with Virtual Box on my laptop, - rsync CentOS 8 root partition on /dev/md0p1, - chroot in CentOS 8 root partition, - configure /etc/mdadm.conf, grub.cfg, initramfs, install

Hi I'm experiencing some problems on a harddisk (it has crashed for no known reason), and in pursuit of getting some of the data out of the disk I'm learning to use the e2fs progs package. Origianlly I used version 1.38, but after experiencing segfaults in e2fsck -which now is solved, I upgraded to 1.39, but now I have hit another problem (on another partition): The partition was

I have just purchased an HP ProLiant HP ML110 G5 server and install ed CentOS 5.2 x86_64 on it. It has the following spec: Intel(R) Xeon(R) CPU 3065 @ 2.33GHz 4GB ECC memory 4 x 250GB SATA hard disks running at 1.5GB/s Onboard RAID controller is enabled but at the moment I have used mdadm to configure the array. RAID bus controller: Intel Corporation 82801 SATA RAID Controller For a simple

Hi, I created a RAID1 array of two physical HDD's with chunk size of 64KiB under Debian "wheezy" using mdadm. As a next step, I would like to create an ext3(or ext4) file-system to this RAID1 array using mke2fs utility. According to RAID-related tutorials, I should create the file-system like this: # mkfs.ext3 -v -L myarray -m 0.5 -b 4096 -E stride=16,stripe-width=32 /dev/md0

Hi, hoping that someone on this list can help me here is the Problem. After a crash it seems the journal could not be recovered. This is what mount gives: root@wuehlkiste:# mount -t ext3 /dev/hdb2 /mnt mount: wrong fs type, bad option, bad superblock on /dev/hdb2, or too many mounted file systems and this is the corresponding logfile-entry: Nov 27 11:16:13 wuehlkiste kernel: attempt to

Note that stride and stripe width only make sense for RAI-5/6 arrays. For RAID-1 it doesn't really matter.

Hi, I have a system with an ext4 filesystem with its journal on an other device (an SSD). Now this SSD dropped of the sata bus so the filesystem went r/o. I would like to remove the journal but it says it can't because needs_check is set. I can't run fsck because the journal is not reachable. Is there any way to solve this? I understand I lost any pending changes in the journal. regards

Andreas, why is it relevant only in case of RAID5 or RAID6? regards, Martin On Fri, Mar 7, 2014 at 5:57 PM, Andreas Dilger <adilger@dilger.ca> wrote: > Note that stride and stripe width only make sense for RAI-5/6 arrays. > For RAID-1 it doesn't really matter. > > Cheers, Andreas > >> On Mar 6, 2014, at 13:46, Martin T <m4rtntns@gmail.com> wrote: >>
