similar to: ext3 inode and journal limitation

Centos 5.1 documentation states that the supported ext3 filesystem limit is 16TB, yet I have a 9.5TB partition that is claimed to be too large: mke2fs 1.39 (29-May-2006) mke2fs: Filesystem too large. No more than 2**31-1 blocks (8TB using a blocksize of 4k) are currently supported. Am I missing something? > uname -a Linux fileserver.sharcnet.ca 2.6.18-53.1.6.el5 #1 SMP Wed Jan

Hello My ssh terminal froze some times, and I was thinking it might be related to centos , but now I found that even ubuntu users experiencing the same problem. does ssh logs any where, and what do you suggest for finding the cause. Thanks

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

Forgive my novice question, but I am a new student of Linux working on presenting the ext3 journaling filesystem to my class. I seek any advice on how to visibly demonstrate (including a purposeful crash of a Linux box) the benefits of ext3 over ext2. I am not worthy to lick the bootstraps of this group, but I beg for any help! The problem I am having extends to even locating the .journal file

My test server was in very eavy load, running kolab's components: postfix, cyrus-imap and openldap A second test machine was sending, and reading emails as fast as it can. The CPU was never idle ! I left the server at about 17H30 and at 22H I find it "uncommitted" (difficult to work when the partition in read-only !) However the mount command report it as RW ! The /boot is still RW

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).

I am fairly new to ISCSI and SAN technology but having recently invested in the technology I am trying to find out exactly what can and can not be manipulated, filesystem wise, without requiring a reboot. I am using the inbuilt software ISCSI initiator and multipathing in CentOS 5.1. My steps so far. Create 10GB volume on SAN # iscsiadm -m session -R # fdisk /dev/mapper/mpath0 # kpartx -a

Hi I need to store about 250.000.000 files. Files are less than 4k. On a ext4 (fedora 14) the system crawl at 10.000.000 in the same directory. I tried to create hash directories, two level of 4096 dir = 16.000.000 but I had to stop the script to create these dir after hours and "rm -rf" would have taken days ! mkfs was my friend I tried two levels, first of 4096 dir, second of 64

Hi Ted and all, I have a couple of questions near the end of this message, but first I have to describe my problem in some detail. The power failure on Thursday did something evil to my ext3 file system (box running RH9+patches, ext3, /dev/md0, raid5 driver, 400GB f/s using 3x200GB IDE drives and one hot-spare). The f/s got corrupt badly and the symptoms are very similar to what Eddy described

We rarely use M$ Windows, but I let my daughter surf pbskids.org while using Windows and a Trojan Horse modified or deleted the user32.dll file. I found the instructions on the Microsoft Support web site, and it would be very easy for me to expand a new copy of user32.dll if I could get the MS WinXP CD to work. It boots OK, I press a key so it will search hardware and it then has hard drive

Hello find /etc -size -1G should return all files less than 1Giga byte in /etc, but return a list of empty file (size=0) find /etc -size -2G work fine and return all the files This works the same on my fedora11 and my centos 5 ! Did I miss something or is it a bug ? Regards -- Alain Spineux | aspineux gmail com Your email 100% available |

Maybe this is a silly question, but i have a few million files i need to delete but i can't just reformat the volume. Right now the fastest thing i can think of is nice -20 rm -Rf /folder-i-want-to-delete is there a better or faster way to do this? Thanks, Jamie

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

Is there a way to create an ext3 filesystem (such as mke2fs will create an ext2 filesystem)? Is there a way to convert a vfat or ext2 filesystem to ext3? Thanks! SJR

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

Hi Everyone, I have a server which has a raid array on /dev/sdb. After a crash I tried to mount the array and it failed with: mount: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or other error dmesg reports: EXT3-fs: invalid journal inode. I tried to run e2fsck and it failed (The output can be seen below). If anyone has any suggestions on how I can restore

Hi all, Is there a command line command that controls which virtual X screen a person is viewing? Sure I can click on one of the 4 virtual X screens but can I control that from the command line. Thanks, Jerry

I'm building a Linux box to act as Proxy/Router/Firewall. I'm using CentOS 4.5, with an "old" motherboard (Asus A8V-X), and two Ethernet NIC, based on a realtek chip, that's widely supported under 2.4 and later kernel (the cards were functioning excellent in another PC whit Fedora Core 1). CentOS detects the on board LAN, but not the other two, in fact, knoppix 5.0.1

Hi. I'm using e2fsprogs 1.23 on a Roswell system with a patched 2.4.7 kernel (using patch ext3-2.4-0.9.5-247) and am trying to create an ext3 filesystem whose journal is located on another device. The incantation I'm trying is: mke2fs -j -J device=/dev/hdc2 /dev/hdc3 I keep getting an error along the lines of "mke2fs: Journal superblock not found". I've tried creating

Hello, How to explain to fdisk that /dev/sda size changed? I increased LUN on storage, reloaded iscsi, did echo 1 > /sys/<something>/rescan. And I see in "dmesg" that kernel found new size of the LUN. But when I type "fdisk /dev/sda" it still shows old size. On /dev/sda1 sits LVM PV and I'd like to resize it instead of adding one more PV to volume group.
