similar to: how to use LVM snapshot with ext3 - VFS lock patch applicability

Hello: We trying to configure one machine (Compaq Proliant ML760) with 8 disks (72GB each disk) with RAID. We are thinking to use ext3 and LVM in RedHat 7.2 for manage one filesystem with 500GB. This filesystems have to store near off 5.000.000 of files. Is this possible? Could I resize the filesystems/volume to 1TB? what are the ext3 and LVM limits? someone have tested sismilar environment? I

Anybody know a way to enlarge a filesystem ext3 without having to unmounted it, when they are still space left in the volume group (when using LVM) ? I will be running large production linux system running Oracle. I can't stop the database everytime I have to enlarge a filesystem. We can do it with all others filesystems (JFS, REISERSFS and XFS) when they are created in a volume group. Why

The tools for raidN (mdadm and friends) don't seem to compile with klibc. Has anyone tackled that, lvm or evms yet in a klibc-based initramfs, or do you usually include uclibc or something when it comes time to get fancy (also, looking ahead to crypto-root and such) Tks, Jeff Bailey

Hi, I've recently been playing about with recent ext3 0.0.6b and lvm 0.9.1 beta7 and am now able to trigger an "Attempt to refile free buffer" assertion. This seems to "only" occur when using ext3 on the root filesystem. Possibly that is related to the fact that the lvm utility I'm using to reproduce this problem is modifying data in /etc. The easist reproduction

Given that no 1.36 has appeared from Fedora Core, I thought I would create the rpm myself. I took the 1.35-11.2 src.rpm from FC3 and updated the spec file for 1.36. However, the build fails. Has anyone successfully created a 1.36 rpm for FC3? If so, what did you need to do? Gene

I think I have this one solved, I hope. I think what Andreas and I are running into are a few different assertions. One being the LVM lvm_do_pv_flush caused assertion which is related directly to invalidate_buffers() being called which then triggers refile_buffer() on a journaled buffer, which appears clean in all other ways according to the checks in refile_buffer(). The following is what

Hi, Can anyone tell me the ext3/ext2/vfs FS specifications: max number of files: ? max number files a dir can have: ? max number sub-dirs in a dir: ? max file size: ? max filesystem size: ? Dongsheng Song

Hi, We will have to go and use SuSE (30 servers) just because ext3 filesystem cannot be increase while the filesystem is mounted. I Don't understand why RedHat do not support filesystems that can do thing that ext3 cannot do. When is RedHat going to understand that in a production environnement (30 servers that is seems will be SuSE) we need extend filesystem online. IBM JS,

I installed a Centos 4.x system using a lvm install across four HDDs. It is my first install using LVM. System had a power-failure and stopped booting up. A new trainee simply took out the HDDs and restarted the file-server on a fresh HDDs. Now the problemis that the four HDDs have data. But the order of the HDDs (of install....1st primary, 2nd primary etc.) is unknown. Earlier we used to boot

I have a system with a large LVM VG partition. I was wondering if there is a way i could share the partition using nbd and have the nbd-client have access the LVM as if it was local. SYSTEM A: /dev/sda3 is a LVM partition and is assigned to VG volgroup1. I want to share /dev/sda3 via nbd-server SYSTEM B: receives A''s /dev/sda3 as /dev/nbd0. I want to access it as VG volgroup1. I am

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 folks, I'm in really big trouble with ext3. At about every second reboot I have files changed on my ext3 filesystem! In most cases I realize that sshd didn't start, and after examination I found that /usr/sbin/sshd or /lib/libutil-x.y.so changed. But when I reboot, everything seems OK. I looked once into the binary, and find parts of syslog in it!!! Horror! And this is a ususal

Hello, I am trying to figure out the best way, how to configure a small cluster with xen and High Availability (Heartbeat). I have two servers and a few virtual machines. What I need is to ensure, that images or partitions of the machines will be mirrored between the two nodes (maybe with drbd?). But that is not all - I also need to enlarge the disks (because of growing databases) of virtual

Hi, I'm looking for some experience regarding using ext3 journaled, ordered or writeback modes through NFS. I wonder what is the best ext3 mode to use with NFS: journaled, ordered or writeback ? And what is provided for atomicity and ordering of write requested through a NFS client with these 3 modes ? As there is some NFS caching and segmentation policies, that are done independently of

Hello guys Does anyone use lvm2 backends for domU storages ? I do and I wanted to use lvm''s snapshot feature to make backups of domUs in background but I got the following problem. When I create a snapshot LV and copy data from it to backup storage it works perfect. Then I do umount and then lvremove. lvremove asks me if I really want to remove the volume and then just hangs forever.

Hello, all. I work with lvm ( kernel 2.4.17 + ext3-2.4-0.9.17-2418p3 patch ) but i can't snapshot a ext3 fs directly # lvcreate --snap --name snap --size +1G /dev/vgtest/lvtest # mount -o ro -t ext3 /dev/vgtest/lvtest /snap /mnt/snap ext3 can't work , ext2 work If I mount readonly the etx3 filesystem, snapshot-it, and remount rw the filesystem ( and ro the snapshot ) it work

Hi, I discovered that SGI XFS for Linux har a utility called xfs_freeze, which freezes the filsystem and makes sure that the filesystem is consistant. It is a bit like a mount -o remount,ro but it does not fail when applications have open files. When we take snapshots of our XFS volume, we do "xfs_freeze -f /mnt/foo; lvcreate -s /dev/vg_foo/bar /dev/vg_foo/bar-snapshot;xfs_freeze -u

Hi Andreas, Any plans to do a release of the online resizing patch for ext3-1.0? I've put off asking about this until Al Viro's superblock handling and other fixes were done, but now that LVM 1.0.1 seems to be approaching a stable and -linus/-ac mergeable state, this would certainly make deploying ext3+LVM a lot simpler.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Searching in the ext3 filesystem mailing list I have seen that there is an indexed directory extension for it. Is this extension stable code ? Has anyone test it ? How may I obtain and install it ? Is it available in any of the last kernel releases ? Greetings. - --- Carles Xavier Munyoz Baldó carles@descom.es Descom Consulting Telf: +34
