similar to: Turn an ext2 filesystem into a component of a mirrored RAID?

We have a large MySQL database currently running on a CentOS 3.x server with an external SCSI RAID device. This is currently an ext2 filesystem because it was migrated once previously from an even older RedHat system. We need to add storage capacity to this database and prepare for additional future growth. One of the options under consideration is to move to CentOS 5 and use LVM. Of some

I often get the message: EXT2-fs warning (device hda6): ext2_fill_super: mounting ext3 filesystem as ext2 I have googled for a reason and a way to solve this - but not found something I could use. Maybe somebody here konws what to do? best regards keld

So still coming up to speed with mdadm and I notice this morning one of my servers acting sluggish...so when I looked at the mdadm raid device I see this: mdadm --detail /dev/md0 /dev/md0: Version : 0.90 Creation Time : Mon Sep 27 22:47:44 2010 Raid Level : raid10 Array Size : 976759808 (931.51 GiB 1000.20 GB) Used Dev Size : 976759808 (931.51 GiB 1000.20 GB) Raid

Our sysadmin was doing midnight work on moving some hardware to new power outlets. We'd recently done a CentOS 5.3 install on one of those machines and then "yum install" with the centosplus kernel and some rpmforge packages. It had been up and running fine for at least two weeks in that configuration. He sent this message: On reboot the root file system seems to have reverted to

hi all, I intend to write a snapshot module for Ext2/3 file-systems. For that i need to make sure that FS is in consistent state before taking snapshot. For ex. in case of UFS, the superblock has a fs_clean flag which is set to be FSSTABLE to tell that its in consistent state. (otherwise its set to FSACTIVE) I m not able to find any such information for Ext2/Ext3. (The

I can't seem to get the read and write performance better than approximately 40MB/s on an ext2 file system. IMO, this is horrible performance for a 6-drive, hardware RAID 5 array. Please have a look at what I'm doing and let me know if anybody has any suggestions on how to improve the performance... System specs: ----------------- 2 x 2.8GHz Xeons 6GB RAM 1 3ware 9500S-12 2 x 6-drive,

Dear All, I have a following query: - My initrd image is created using ext2 filesystem. - The filesystem type of / is specified as ext3 in /etc/fstab file. - I dont mount the real root during execution of linuxrc because I referred some documents saying that if you dont mount real root from linuxrc the kernel will mount it after linuxrc is finished. - The system boots up successfully, mount

Hello, I've got a 4.4 box that i'd like to implement software raid on. Does anyone have any experiences with this? Thanks. Dave.

I have a CentOS 4.2 system that was set up VERY quickly following the demise of its former life as a CentOS 3 server - you don't want the full story, but it had to be done quickly to get a company up and working following a slight disaster involving an electrician, a portable appliance safety tester and a pulled power cable - anyway, here's where I am at... Everything is running fine but

Dear list, I thought I'd just share my experiences with this 3Ware card, and see if anyone might have any suggestions. System: Supermicro H8DA8 with 2 x Opteron 250 2.4GHz and 4GB RAM installed. 9550SX-8LP hosting 4x Seagate ST3250820SV 250GB in a RAID 1 plus 2 hot spare config. The array is properly initialized, write cache is on, as is queueing (and supported by the drives). StoreSave

Hi, I am looking into purchasing a new server. This server will be mission-critical. I have read and somewhat understood the theories behind RAIDs 0, 1, 5, 10 & JBOD. However, I would like to get some feedback from those who have experience in implementing and recovering from a HDD failure using RAID. Hardware specs include:- Dual Xeon 3.2 GHz 2 GB RAM I would like to implement

Hello, I had a scientific linux 3.0.4 system (rhel compatible), with 3 ide disks, one for / and two others in linear raid (250 gb and 300 gb each). This system was obsoleted so i move the raid disks to a new scientific linux 3.0.7 installation. However, the raid array was not detected ( I put the disks on the same channels and same master/lsave setup as in the previous setup). In fact

Hi, I want to change my running software raid1 from ext2 to ext3. I'am currently running RH 7.1 with 2.4.18. The raid constist of two 40GB disks on a seperate UDMA Controller (HPT370). The system is installed on another disk. Can I just use tune2fs -j /dev/md0, or do need to rebuild the raid from scratch with ext3? Many thanks for your help! Regards, Ingo
