similar to: ext3 + loop + journaling

Hi. I am using a large storage which is ext2 file system of 1T byte. It has many file types, doc, mail data, zip, etc. It doesn't have a database file. I want to change the file system from ext2 to ext3. It also can't divide to any partitions. How to decide journal mode and journal size? Please advice to me. Recommend a journal mode. (orderd or journal) Recommend a journal

Hello, Is there some document about ext3 performance tuning and choosing the right type and size of journal? Except RedHat's white paper. From what I read I understood that for typical operations data=ordered is prefered. For the cases when there are many writes not appending to files data=journal is the choice. And if I want to get the most performance or in case where program is doing

hi i got 2 questions and maybe someone could shed some light: a) i'm using kernel 2.4.17 and use ext3 in it. is it possible that the whole system is slower than with ext2? i switched back to ext2 (great feature!!!) and the system's response seemed somewhat better. should/could there be such a effect as double writing of journaled data? i didnt activate debugging (jbd). b) is reiserfs

Right now I'm building a 2.4.17 kernel on an HPPA Linux system. The kernel it ships with supports ext2 only.

I am using kernel 2.4 and ext3 fs on all partitions. I recently suffered a power outage while working on some documents. Some of them had previously been saved other had not. In either case none of the new data was restored. I am also finding other strange disapearrances like bookmarks and panel applets. My understanding of the ext3 fs is that these documents should have been restored

I am running postfix on RH machine. decided to upgrade one of my machines from 7.1 to 7.2 - performance drop of 75 percent !!!!! moved back to ext2(remount partition as ext2) - performance is back. on the 7.1 upgraded to ext3 (only the disks), rebooted - performance drop of 70 percent... used a 2.4.17 kernel compiled by myself - a little faster then the last RH kernel, but still runs at third

hello, i just wanted to know how to move files from the master node to slave nodes...for example i have 10 files in the master and i want to move 2 files to each slave node...how do i do that....i have redhat7.2......i tried rpc but it said command not found...i am using a beowulf cluster. your's sincerely, devi vijay Get Your Private, Free E-mail from Indiatimes at

Where can I find a patch for ext3 fs for kernel-2.4.2. Currently I'm using RH7.1 I dont want to upgrade to RH7.2!!! I just want to applay the ext3 patch for kernel-2.4.2 compile and use it. Thanks in advance! Sanat

Hello All, Yesterday, one of our customer's cluster(2 box) server goes down after a I/O error during the backup procedure. When we turn on the cluster again, the 600M database file have been lost, disapear. Now, I'm with one of the disks (the other was used to rebuild the database server) and need to know how can I recover any piece of data from the disk. After the crash we mount the

I am having major problems on one of my file-servers. I have the root filesystem on an Ext3 software RAID 1 between four SCSI drives. It had been running for about two months without problems, but today I found it was having some trouble with unlinked inodes and I/O errors on certain files. I took it down to single-user mode, and ran fsck on it. That operation mixed up files like /etc/hosts with

Dear ext3 hackers, I'm running a RH 7.2 system with kernel 2.4.18 an a ext3 fs. Yesterday night this machine, which is being tested with a Proxy server (Squid), was accidentally power off (electrical outage). Now, when the system is booted, I have a ext2 'read only' fs; fsck doesn't find any kind of problem (automatic or manually executed: fsck -t ext3 /dev/sdb1). The only fstab

Hi! I would like to know how well ext3/(ext2) will tolerate underlaying errors (I am planning to use loop-AES backed ext3 fs). So if there is 1024 bytes corruption of data what will be the worst case: - If this data belongs to some file, this part of data(file) has been lost? - If this data belongs to superblock, I have to repair ext3 and use another superblock? - If this data belongs to

Everyone, We just had a pretty bad crash on one of production boxes and the ext2 filesystem on the data partition of our box had some major filesystem corruption. Needless to say, I am now looking into converting the filesystem to ext3 and I have some questions regarding ext3 and Linux software RAID. I have read that previously there were some issues running ext3 on a software raid device

Hello, I converted one of my servers to ext3 and load average numbers went up. Now they are ~2-3 while on ext2 LA was <0.4. And I'm constantly seeing processes and kjournald in D state. vmstat confirms that. But even in such LA CPUs are ~99% idle. What can be wrong? RedHat 7.1 kernel 2.4.18-18.7.xsmp.

Lo, Actualy i'm looking for documents about journalised file system, in order to be able to compare them self. I need accurate information if i want to make a good study. Thoses informations have to permit me to get answer about table like this : Features \ fs | xfs | ext3 | jfs | reiserfs | ------------------------------------------------- chattr | ? | Y | ? | ?

Hi! Today I switched over to devfs. I'm on Debian unstable, installed devfsd, installed a kernel with devfs support and "devfs mount on boot". Reboot, devfs is being used. All over a sudden, dmesg reports: Linux version 2.4.21-ac1 (root@hummus) (gcc version 3.3 (Debian)) #1 Sun Jun 15 19:06:13 CEST 2003 ... kjournald starting.

I'm lacking some understanding of how to tune / when to tune /proc/sys/vm/bdflush Where can I read up on this? Our current problem: Load is low, but ever so often the system decides to do some serious disk I/O which causes all processes to wait for disk I/O -- load explodes (rises linear up into the 20-30ies) just to fall linearly (spelling?) right after that. We think there might be some
