General :: Know Ext4 Changes In New Kernel?
Dec 5, 2010For example: [URL] . New version, but nothing about ext4. Does this mean v2.6.36.1 has nothing new about ext4? Nothing was improved in ext4 in this version?

Fedora :: Can't Mount Ext4 Logical Vol Under New Kernel?
Dec 5, 2009I have 250Gb, 500Gb and 1Tb drives concatenated together as one volume group (span) with a logical volume (spanvol). Under kernel 2.6.31.5-127.fc12.x86_64 it mounts totally fine. However, under 2.6.31.6-145.fc12.x86_64, I get this:-
[root@undertaker ~]# mount -t ext4 /dev/mapper/span-spanvol /home
mount: wrong fs type, bad option, bad superblock on /dev/mapper/span-spanvol,
missing codepage or helper program, or other error

Slackware :: Compiling Kernel - Ext4 Is Read As Ext3?
Jan 25, 2010I compiled a kernel using a previous kernel config after I switched to the ext4 file system. Previously it was using ext3 and the kernel compiled and ran fine. I added support for ext4 to the config but when I went to boot I had a kernel panic. The error was "kernel can't mount vfs on (8,5)". Root is on sda5, I don't know what the 8 is. I started over, using mrproper and made a new config, but got the same error. I created an initrd with the ext4 file system but then the kernel said it couldn't mount root on ext3 because of unique options. (something along those lines) I booted back into the default kernel and saw that it had a similar error right after the bios check, but it loaded fine. I'm wondering why the kernel is saying that the ext4 file system is ext3.

Apr 20, 2010telling me if this behavior of my openSuSE 11.2 installation is normal? I use a 64-Bit openSuSE 11.2 with kernel 2.6.31.x with root partition ext4. After adding and updating from repository kernel:/HEAD/etc to 2.6.34-rc4 I can not boot anymore due to a lack of module ext4. I thought today ext4 is stable and fix built-in in the actual kernel releases, isn't it? The error message at boot time: FATAL: Module ext4 not found. Which is right because in /lib/modules/<kernelversion>/kernel/ there is NO 'fs' subfolder. Isn't the kernel:/HEAD/ repository the official update path to get a newer major kernel? (besides openSuSE's Updates for security reasons) Do you know how I can fix it without self-compiling?

View 5 Replies View RelatedGeneral :: Regarding Raid 5 And Ext4 Options?
Nov 16, 2010I'm currently building a Raid5 Volume Set (HW-Controller, 3 disks). After some diskussion I decided to don't use a partition since I don't see any disadvatages writing the filesystem (ext4) directly onto the device.
Because I plan to expand the volume set with 2 more hard disk drives, respectively the filesystem, to get the complete disk space available I read the ext4 manual. There is an extended Option called max-online-resize with the description:
Well, although I've searched for more details on the internet I can't find any. Primary in which case is it usefull to set this value because later resizing should be possible without to set this value. Maybe it accelerates the resizing process?
Next, I also plan to use the options stride=stride-size and stripe-width=stripe-width. Is it advisable to set these values for the final volume set (Raid5 with 5 drives) or do I have to set it for the first volume set (Raid5 with 3 drives) and then changing these values during the later resize process for the filesystem? (I personally prefer the first method).
General :: Grub 97 And Add Ext4 Support?
Jan 6, 2010I have slackware 13 ext4 partition. Debian lenny ext3 partition. and a /data ext3 partition Debian contains the grub boot loader i've been using to boot slackware. I'm going to wipe debian and I installed grub to /data with knoppix cd. Grub on debian booted into slackware just fine, but the grub I installed (onto data partition) with knoppix live cd does not find the slackware kernel. I am using the exact same menu.lst. apparently debian grub had ext4 support, but knoppix does not. both are grub .97. Is there a way to add ext4 support?

General :: Hard Drive Thrashing With EXT4
Nov 1, 2010I'm dual booting Ubuntu 9.04 and 10.04 on an ASUS P5VD2-MX SE mobo with 3 hard drives, a couple of DVD writers and a multi memory card reader (USB).
The hard drives are:-
1 250Gb SATA MAXTOR STM325082
1 80Gb PATA HITACHI IC35L090AVV207-0
1 80Gb PATA MAXTOR 6Y080P0
9.04 lives on 2 ext3 partitions of the 250G SATA
10.04 on the 2 ext4 partitions of the 80G MAXTOR
The HITATCHI has 1 ext4 partition mounted as a common data area for each O/S
The 250G drive has GRUB Legacy in the MBR with its files in a small ext3 primary partition chainloading the 2 O/S's, GRUB Legacy for 9.04 and GRUB2 for 10.04. It also contains the common SWAP partition (primary)
When I boot into 9.04 everything works as expected with as far as I can see no unusual disk activity even when the ext4 data partition and the 2 10.04 ext4 partitions are mounted. When 10.04 is booted however, after about 5 minutes (irrespective of whether or not the other partitions are mounted) I see the hard drive activity light come on and stay permanently on. The system monitor shows nothing unusual. dstat doesn't give any clues either. I've tried running iotop but it fails with a missing CONFIG_TASK_DELAY_ACCT error.
Is this a known problem with ext4, should I rebuild 10.04 onto ext3 partitions? Are there some special ext4 mount parameters I should use? (I simply copied the fstab lines from 9.04 and just changed ext3 to ext4). I've read that the journaling process(es?) for ext4 by default commonly access the drive(s) every 2-3 secs but that should just cause a flicker surely.

View 4 Replies View RelatedGeneral :: Instructions Work When Turning Of Journaling On An Ext4 SSD?
May 27, 2010I have an Acer Aspire One with an SSD for storage. I recently installed Ubuntu on it and chose ext4 for my filesystem. Then I read that journaling on an SSD isn't the best idea, so I will try to disable journaling and I have found these intstructions [URL]..
# Create ext4 fs on /dev/sda10 disk mkfs.ext4 /dev/sda10 # Enable writeback mode. This mode will typically provide the best ext4 performance. tune2fs -o journal_data_writeback /dev/sda10
# Delete has_journal option
tune2fs -O ^has_journal /dev/sda10
# Required fsck
e2fsck -f /dev/sda10
[Code]...
I will use them on my boot partition. Are there any particularly bad parts here, or are there any missing steps? Will my boot partition be fit for being on an SSD after this? Or should I consider switching to ext2, or even reinstall it all and choose ext2 at partitioning time (I'd rather not though, since I've configured quite some stuff already)?
General :: Ext2 Or Ext4 For Bootable USB Flash-drive?
Jan 26, 2011I want to install Ubuntu to a USB Flash drive (so I have my Desktop everywhere and can customize it as I want). I'm still choosing what's the best filesystem for the USB; Ext2 with no journaling or Ext4 with journaling but performance increase? I know that journaling will probably reduce the life of the USB flash drive dramatically, so is Ext2 the obvious choice? Or is it a bad idea to install Linux (Ubuntu probably) on a USB Flash drive? I tried running a live CD from the USB drive, but it wasn't very customizable - which is the point of carrying my OS with me.

General :: Recover Data From Repartitioned EXT4 Filesystem
Aug 5, 2011On my drive I had 2 partitions for an Ubuntu 9.04 (swap, /) and one partition for Windows. I figured out that I should upgrade my Ubuntu, so I deleted the "/" partition and in its place created 2 new partitions (/, /home) .
After installing the latest Ubuntu 11.04, I realised that although I had backuped everything I needed in a 2nd disk and I could access those folders and their data from my Ubuntu 9.04, both my Windows and the 11.04 can locate neither the folders nor the data now. I have no idea why this happened (perhaps some issue with the mounting?) I have tried the trial version of Stellar Phoenix linux data recovery tool, but it cannot locate the old partitions.

Dec 29, 2009How can I format a USB hard drive to ext3/ext4 or whatever file format and have full permission to read, write and execute all files afterwards? When using the command line (as ROOT of course) mkfs.ext3 /dev/sdb? Restricts the rights to ROOT as does the procedure gParted. The man mkfs did not help much. Configuring the fstab- file is a bit of a hassle, so it would be nice, if there was an option to set the permissions "correctly" right from the beginning. Setting Ubuntu (I'm using Ubuntu 9.10) up, so that it mounts USB devices not as ROOT as default but giving all users all permissions seems to be really complicated, as a guy from my local LUG told me.
