Hi There, I re-installed Centos 4 on a box previously running x86 Solaris 10. After a reboot a got a BAD PBR SIG so I used rescue mode and grub to install a boot loader on each of my software-raided disks. Which works fine and allows me to boot ok. My question is, what happened to /etc/raidtab the machine boots ok and lists all the raid-1 devices I set up in the install (including the

Hello, I wonder if has seen a problem of the sorts I am describing as at the moment it is driving me nuts. We have an array of LSI disks (Hardware Raid 5) which are attached to a Linux node. The Node has a LSI929 dual fibre channel card that has a channel attached to controller A and B of the array. So we have a list of devices under /proc/partitions mapping what we are expecting to see

When a new system CentOS-4.4 is built the swap partition is always reversed... Note md3 below, the raidtab is OK, I have tried various raid commands to correct. swapoff -a raidstop /dev/md3 mkraid /dev/md3 --really-force swapon -a And then I get a proper ourput for /proc/mdstat, but when I reboot /proc/mdstat again reads as below, with md3 [0] [1] reversed. [root]# cat /proc/mdstat

Hello fellow xenophiles and happy new year! I''ve documented the install procedure for a prototype server here since I found no similar document Anywhere on the net. It''s a Sarge-based Domain0 on linux root raid from scratch, using LVM to store the data for the domU mail server and its mailstore. I humbly submit my notes in the hope that they are useful to some weary traveller.

Consider this section: http://www.tldp.org/HOWTO/Software-RAID-HOWTO-4.html#ss4.14 I have not done this before and I'm leary about Step 11 which is resizing the filesystem after doing a mkraid command. This howto lacks any ext3 documentation. Some questions I have are: 1. Should I convert back to ext2 on all my filesystems before I do a mkraid? 2. If I leave the system at ext3, will the

Hi all, hoping someone has some insight on this issue. I am working on a first install of RAC. I have installed OCFS 1.0.9.4 (upgraded from 1.0.8 before installing the rest of the oracle software) on a 3 node RedHat AS 2.1 cluster. The kernel is 2.4.9-e.25.enterprise. Oracle software installed 9.2.0.4. I fdisk'd the storage devices, mkfs.ocfs on the partitions, and mounted successfully on

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

Hi, I'm attempting to get openssh-3.4p1 up and running on our DEC/Compaq Alpa workstations. They are running Tru64 Unix 5.1A. I compile the package myself. Openssh-3.1 worked perfectly, with the default sshd_config file. Openssh-3.4p1 works, if I set UsePrivilegeSeparation to "no" in the sshd_config file. NOTE: I have a secondary issue with the ListenAddress default setting

Hey all, well, first of all (even if it's quite late as it's in version 3.0.7 already): thanks a lot to all who are developing and supporting Samba! I'm new to Linux and I really like the way things are happening on this OS. But now, I've reached a point where I have to raise the white flag... It seems to me like - at least my - software raid can't dance Samba. I've got

Hello all, I've got CentOS 5.2 installed on an old Pentium III server. The server is used by a club at my school, and they are rapidly running out of room on the internal IDE drives that are configured in software RAID 1. I have a Silicon Image SATA controller in the server, and I was planning on adding two more SATA hard drives to the computer. Is there a GUI like Disk Druid for

Hello Everyone, First time CentOS poster :) I have CentOS 4 installed on the head node of a Sun Gridengine cluster set up in a RAID. The head node has four hard drives, and I assume that drives 1 and 2 are in a raid and then drives 3 and 4 are in another raid. I was trying to expand the OS partition on drive 1 because it was full. I took drive 1 out, put it in my Fedora 8 box as a secondary

Sorry, this is going to be a rather long post...Here's the situation; I have 4 IDE disks from an old snap server which fails to mount the raid array. We believe there is a controller error on the SNAP so we've put them in another box running CentOS 5 and can see the disks OK. hda thru hdd looks like this Disk /dev/hdd: 185.2 GB, 185283624960 bytes 255 heads, 63 sectors/track, 22526

Friends- I''m happy to annouce the first alpa release of BackgrounDRb. This is a small framework for managing long running background tasks that allows for ajax progress bars and more. It also serves as an Application wide cache and context store for when you need something like sessions but shared between users and multiple backend processes like fcgi''s or mongrels.

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

Hi, Doing some extensive benchmarks on BTRFS, I encountered a kernel bug in BTRFS (as reported in dmesg) Maybe the information below can help you making btrfs better. Situation Doing an intensive sequential write on a SAS 3TB disk drive (SEAGATE ST33000652SS) with 128 threads with Sysbench. Device is connected through an HBA. Blocksize was 256k ; Kernel is 3.3.0 (x86_64) ; Btrfs is version

I am starting to see a few issues with OCFS and 9.2.0.3 RAC on redHat Linux AS 2.1. Wondering if there is anyone out there experiencing similar issues... a few pointers to the issues.. 1. OCFS read/write performance is way lower than a read/write to a raw device.. i can give you some comparison numbers.. 2. Writes to shared disk with ocfs would get locked up by one server.. it doesnt have to

Sorry for cross posting, but I somehow came to think that this question might possibly be more suitable in this mailinglist. I am currently fiddeling around with Fedora Core 2. Does anyone of you have any pointers on where to start reading to compile OCFS 1.0.13 on a 2.6.8 kernel? Is it at all possible?
