I've Managed to over write my MBR and offcourse all my partions are gone (stupid me). i kept a backup of my MBR but silly me it's on the same disk that died. i have a rescue disk is there any way i can read from /dev/hda and go through the whole disk (RAW DATA) searching for "mbr backup file" and then read it. I am using EXT3 with slackware 8.1/RH 7.2 I am sorry my spelling is

I'm not sure if this question makes sense, but here goes. We have the need to periodically check for newly created/modified files in a rather elaborate and well populated directory structure. I don't believe that simply walking the directory and checking stat's is the answer, given that I need a process that will impose minimal performance degredation on the system. Would it be

hi :) when using ext3, i can't get my hard disks to go to standby mode any more. i am using timeouts set by hdparm with 2.4.18 kernels. even when i issue a standby command manually, the disk spins up again after a few seconds. however, (to my knowledge) no user space program accessed this disk at that time. i suspect ext3's journal to be causing the disk accesses. is that possible?

Hello to everybody here, We have a strange problem with ext3. df reports 28 of 30 GB to be used (rest may be slack) which it calls 100% used. But with du we can only find 13 GB, most of it actually in pretty large files (archives). Where are the other 17 GB gone?

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

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

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

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

[ If this is explained somewhere else (HOWTO or FAQ), please give me a pointer. ] Is there any way to mix loop-device (and in particular) loop-AES and ext3 together in data journaling mode? Ie. bottom -> to -> top ext3 - loop-AES - ext3 raw - loop-AES - ext3 Or am I shooting myself to leg, I am? BR, Jani -- Jani Averbach

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 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

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 there, I've been using ext3 on RedHat 7.1 for some time and I'm very pleased with the result. Thanks for all the hard work people have put in it! I have however one problem: when the machine boots up it tries to load the mcd and mcdx CD-ROM drivers (AFAIK they are old non-standard CD-ROMs). It does this from rc.sysinit right after loading usb devices. The machine started to do

Hi there, First of all thanks for all the ext3 development! I run it on my laptop and it has saved me many times from lengthy fscks :-) However, I have observed that whenever something is doing a lot of writing to an ext3 filesystem other processes that involves I/O on the same disk are blocked for long times (often in the 10-30 secs range). For example, if I cp a 1.5 Gb file from one ext3

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

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.
