similar to: viewing ext3 journal

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

Hello! I need to write a user space tool that can dump logical block addresses used by every file in a ext3 file system. For example, if file foo uses LBAs 2,3 and file bar uses LBAs 100,102,156, then the ouptut should read: FILENAME LBAs foo 2, 3 bar 100,102,156 Is there a tool that exists that can do this? If not, what would be a good strategy to write this tool. I am

Continuing on with my earlier post . . . after looking through code of JBD, is the following perhaps the difference in why the md5 values differ; When a journalled filesystem that uses jbd is mounted the journal b_count is incremented by one? *EVEN* if the volume was mounted read only, this b_count is still increased by one? curious as ever! lt __________________________________ Do you

Hi I want my lustre do such things during OST failed: if some file has stripe data on th failed OST, any operation on the file will return IO error without blocking, and also at this moment I can create and read/write new file or read/write files which have no stripe data on the failed OST without blocking. What should I do ? How to configure? thanks! swin -------------- next part

Is there any way to query the size of an existing journal? I have heard a number of sizes thrown around as defaults, but I need to be able to reliably get the exact journal size.

Hello, I''ve several problems with quota on our testcluster: When I set the quota for a person to a given value (e.g. the values which are provided in the operations manual), I''m able to write exact the amount which is set with setquota. But when I delete the files(file) I''m not able to use this space again. Here is what I''ve done in detail: lfs checkquota

Hello, We have run and stopped by chance command "fsck -y" on one of our raid disks (with ext3 file system). After that we have found that SOME files disappeared (they are not seen in the directories where they have been before). The data are extremely important and contain a lot of programs, scripts for some data analysis and very hard to recover by hands. I have run ''fsck

Hello CFS, I was wondering if the new SLES10 kernel will be part of the 1.6.4 release. It appears to be tracked by: https://bugzilla.lustre.org/show_bug.cgi?id=13874 As this contains a major security fix (privilege escalation), it is a mandatory upgrade in many places and it would be nice to not have to roll our own kernel. Thanks, Kit

Hi, perhaps dump question: I'm using ids system and doing file monitoring. If any file changed, i see it. Recently i saw inode change of /etc/shadow. One user was added. So what might be reason for inode change of any file? Does inode size grow by-and-by? I think not. Or might only reasonable cause be that this file was deleted and recreated again? regards -------------- next part

We are running Zope behind Squid 2.4Stable6 with squid in acceleration mode. The squid box (dual Pentium III 1 GHz, RH 7.2, Linux 2.4.9-21smp, 2GB Ram) has during busy hours a normal load of 0.2-0.3 . From time to time we see spikes over some hours where the load average of the machine is higher than 1.5 although there are no spikes in the CPU utilization. Also there is no increase in the number

I am running on CentOS 5 distribution without adding any updates from CentOS. I am using the lustre 1.6.4.1 kernel and software. I have two NICs that run though different switches. I have the lustre options in my modprobe.conf to look like this: options lnet networks=tcp0(eth1,eth0) My MGS seems to be only listening on the first interface however. When I try and ping the 1st interface (eth1)

Hello, I have 2 boxes with 1.5TB storage with ext3 fs, and the kernel is 2.6.11.8. I'm using E2fsprogs 1.37 for FS creation. And, Filesystem revision #: 1 (dynamic) There are 2 scenarios: 1. All SATA drives, RAID5 2. All PATA drives, RAID5 and wrapped in log volumes. I'm having lots of issues with fsck. I did search, but somehow not getting the right information. needs_recovery

This may be in the documentation. If so, I missed it. If a site has multiple Lustre file systems, the documentation implies that there only needs to be a single MGS for an entire site (regardless of the number of file systems). However, I also know it is fairly common to have a combined MGS/MDT. So here are the questions. 1. If we are going to have several Lustre file systems,

A few wild ideas/questions : 1) Is there a way to check the size of the journal of an ext3 filesystem ? I mean - the actually used size ; not the total size of the journal. 2) Would it be difficult to implement "freeze" of ext3 filesystem - that is, blocking all I/O to the filesystem until it's "unfrozen" (XFS can do that), for two purposes : A/ allowing

In 1.6.0, when creating a MDT, you could specify multiple --mgsnode options and it would failover between them. 1.6.3 only seems to take the last one and --mgsnode=192.168.1.252 at o2ib:192.168.1.253 at o2ib doesn''t seem to failover to the other node. Any ideas how to get around this? Robert Robert LeBlanc College of Life Sciences Computer Support Brigham Young University leblanc at

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
