I have configured a "Syslog" server on /var directory as a separate ext3 partition - to receive the logs and events from the clients & the firewall as well. The directory needs to grow dynamically as the logs are populated. Is there a way i can make the filesystem grow dynamically as and when the directory is full.

View 2 Replies View RelatedI just rebuild the kernel for slackware 13, everything works, but root file system which is ext3 is mounted as ext2. Normally I've build ext3, ext4 and so on as modules, not in the kernel... but if I do this, then the kernel mounts the file system as ext2, which is build in the kernel. I also modified rc.modules so I can make sure that ext3,ext4,jbd are loaded, but it doesnt work.
View 2 Replies View RelatedI used the ext3 format when I formatted my partition prior to installing Ubuntu10.10. I had accidentally deleted a file and began the process to get it back. It wasn't critical but helpful to recover the file. To make a long story short I ran into to some unexpected road blocks. I tried to use PhotoRec to get the job done but with no success.
I'm just looking down the road in the event I might have to recover something important.If it would be better going back to the Fat32 file system I would rather do it sooner than later. Just as a side note I am dual booting between linux and windows.
How would I format my partition into a ext3 file system?
View 1 Replies View RelatedI am using Ubuntu since release 8.10, but it is first time when i can`t solve problem
when i tried to create new NTFS partition on unallocated disk space with Paragon Partition Manager (damn, that was stupid). Process was aborted with error (later i finally made it with Gparted without problems)
After reboot mine Ubuntu say:
Code:
Errors were found while checking the disk drive for /
Press F to attempt to fix errors, I to ignore, S to skip mounting or M for manual recovery. I pressed "F" but that had help only for a boot and doesn`t really fix error :`(
Later i booted from liveCD and had checked partition (/dev/sdb1; file system - ext3) with gparted (result - aborted fixing process with error) Now i can`t even boot from that partition and even mount it from other linux system.
mine fdisk -l
Code:
/dev/sdb1 * 1 5957 47849568 83 Linux - problematic partition (unmountable)
/dev/sdb2 5958 29983 192988845 7 HPFS/NTFS

PhotoRec recover most of my files, but i need complete partition.
I need evaluate the ext3 file system performance; i need define:
- services provided
- parameters and
- the performance with different parameter values; for example, changin the value of the "data" parameter (journal, ordered, writeback).
I do not know what services ext3 provides. Well, i know intuitively that it provides services to read, write and erase files. But, there are anything more?. Where can i find the API?. Is the ext3 file system POSIX compliant?
I accidentally formatted a HDD when I meant to format a USB thumb drive. The HDD is a 250GB drive that had about 180GB of data in the EXT3 format. I was actually attempting to make a bootable USB thumb drive with TRK (Trinity Rescue Kit). Kind of funny/ironic to mess up a drive while trying to make a rescue disk. Anyway, as soon as I realized what had happened, I pulled the drive out of the computer to make sure I didn't do anything else stupid to it. I have been searching for some way to recover and haven't really found much. There are a lot of programs to get Windows data back, but I haven't seen anything specific on the EXT3 file system.
View 4 Replies View RelatedI'm trying to mount a second hard drive as a ext3 (rw_acl,user_xattr). I type the ff.:
# mkfs.ext3 -c /dev/sdb1(it seems to create a file system from this 2nd HD)
then type:
# mount -v /dev/sdb1 / type ext3 (it seems to mount it)
But when I check the ext3 systems with typing:
# mount -t ext3 (to check the list of ext3 devices, it gives me this)
/dev/sda1 on / type ext3 (rw,acl,user_xattr)
/dev/sda2 on /home type ext3 (rw,acl,user_xattr)

I have accidentally removed vmware virtual disk, my host operating system is RHEL5.2 with ext3 file system, i have used photorec, magicresue and foremost but still no luck to recover the vmdk file. i have seen in foremost configuration file that there are some predefined files (ex- doc, pdf, jpg, avi, zip, etc),
1. is there any way to add vmdk file extension on that configuration file?
2. if yes how can i do ?
3. by adding vmdk on configuration file, can i specifically use recover option for vmdk?
I have a weird performance issue with a centos 5 running a nfs server and a rh8 client. I think the fact that it is rh8 client should be downplayed. It is just that with rh8 client the performance degradation seems more clear. See test details below OS in server is Centos 5 x86_64 kernel 2.6.18-92.1.22.el5
1Gb connection between machines File to test over NFS is a 1GB file. First of all I wanted to measure how the network alone performs while using NFS. So in the server side I run a "cat" command on the 1GB file to /dev/null. Please note that the disk read speed is about 98MBs. At this point the file system has the 1GB file cached in memory. In the client side a "cat" on the same file gives me a speed of about 113MBs. It seems then that the bottleneck in this instance is the network and it is very close to nominal speed. So the network performance is really good. (BTW I know that the server got that file from cache because a vmstat or iostat shows no disk activity.)
The second test is reading from disk with no caching involve. In the server I flushed the 1GB file from the memory. For instance by reading another 5GB file and I repeat the same thing as above in the client (a cat on the 1GB file). Now, the server has to go to disk.(vmstat or iostat shows the disk activity). However the performance, now, is about 20MBs, I was expecting something closer so 90MBs. (since the reading speed in the server in the first test showed 98MBs).
This second test was repeated for ext2, ext3, xfs with no significant differences. A similar test using a RH8 NFS server and client gets me close to 60MBs for a 1GB file not cache by the file system in the serverSince network speeds and disk read speeds are not the bottlenecks ... what or where is the limiting factor then?

I have an image of an ext3 file system done with dd. I know that the file system is corrupted but I want to try to recover some files. Whatever I dd it again to the original partition or assign the dd image to a loop device, that's what happens:
- dumpe2fs -h gives me a valid ext3 superblock.
- as I try to mount the device read only, it fails with a bad magic number error.
- executing dumpe2fs -h again gives bad magic number error.
- trying debugfs or fsck with backup superblocks fails the same way.
For me it seems that in spite of mounting the device as read-only, mount command do something wrong with the superblock as before the mount the superblock is correct and it's there.
I'm looking for insite on how it might be possible to grow an existingvolume/partition/filesystem while it's in active use, and without having to add additional luns/partitions to do it.For example the best way I can find to do itcurrently, and am using this in production, is you have a system using LVM managing a connected LUN (iSCSI/FC/etc), with a single partition/filesystem residing on it.To grow this filesystem (while it's active) you have to add a new LUN to the existing volume group, and then expand the filesystem. To date I have not found a way to expand a filesystem that is hosted by a single LUN.
For system context, I'm running a 150 TB SAN that has over 300 spindles, to which about 50 servers are connected. It is an equal mix of Linux, Windows, and VMware hosts connected via both FC & iSCSI... With both Windows & VMware, the aforementioned task of expanding a single LUN and having the filesystem expanded is barely a 1 minute operation that "Just Works".If you can find me a sweet way to seamlessly expand a LUN and have a Linuxfilesystem expanded (without reboot/unmount/etc)I have cycles to test out any suggested methods/techniques, and am more than happy to report the results for anyone else interested. I think this is a subject that many people would like to find that magic method to make all our lives much easier
I installed CentOS 5.5. After install, I decided to put 3 identical disk for raid 5. All the disks are IDE disk. Then I put a sata disk and partitioned it to add another partition to the raid 5 array. Everything works fine until I rebooted my system. After reboot, the sata partition I added into raid 5 is showing removed. I had to readd it using "mdadm --add" to make raid 5 array works.

View 3 Replies View Relatedi needed to change my external hard drive's file system from ext3 to fat32, to use it in windows, which i did the simple way: i shrunk the ext3 partition, made a fat32 partition, copied the files over, removed the ext3 and made the fat32 bigger. unfortunately, while gparted was making the partition larger, my computer shut down. i lost all my files and the partition messed up immediately. i made a new fat32 partition, after deleting the old one, but noticed that gparted was showing 100 gigs already in use (???). so now i have a 300 gb hard drive with only 200 gb i can use; i ran df to make sure gparted wasn't messing up, but indeed it shows the partition as being only 200 gigs in size. i haven't tried making any other kind of partition yet, such as ext3, for fear of losing my files again, and because it wouldn't be permanent anyway, because i need those files in windows and stupid microsoft won't make their OS ext3 compatible.
