similar to: LVM change disk

Dear All, I plan to replace an error disk that is part of an LV. from LVM how-to it could be done with using pvmove to move all PE from old disk to new disk.But the howto also said that pvmove is slow. Anyone has experience using pvmove on 2TB disk? Is it possible to make all PE on the old disk empty so I don't have to do pvmove (assuming that I can make a free space >= 2TB). Thank you in

Hi All, On my gateway server I'm Installing CentOS on a flashdrive. is that a bad idea? the server keep hang, I can ping the server from the LAN and from the internet, the internet connection from LAN to internet is OK but another service is down, ssh, VPN (PPTPD) and another service. Even the console is unresponsive so I have to reset the server. Last time when I still can do SSH to server

Dear All, I have one VG with one LV inside consist of four disk (and four PV) somehow the UUID is changed. I try to restore with the last known good configuration and use pvcreate --uuid xxx --restorefile xxx but I think when I first time do it I did use wrong UUID for two device. but haven't only using command above and haven't used vgcfgrestore. After carefully read the configuration,

Hi. I have a volume group (let's say) vg_data. It consists from /dev/sdd5 sdd6 sdd7 I added sdc5 Now I want to remove (free) sdd7 and you is to for RAID partition. What are the commands (ordered) I need to perform? I failed to find clear howto. vg-data has only one partition, total size is over 1TB, free space is about 500GB so

CentOS Community, It is to my understanding that the /boot partition should never be placed on LVM and should be a physical partition on the hard drives (or on top of a RAID array). Is this an accurate statement? Also please advise if the SWAP filesystem is safe to be placed under LVM, or if this should be a hard partition / hard limit as well. I am unsure if boot issues or any filesystem issues

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

Hi guys, Logrotate is checked every day by cron.daily, right? I notice in logrotate.conf by default it's weekly. If I change it into monthly (now, on 12 of Feb), when will it do the monthly rotation? a. On 12 of March or b. On 1st of March? Thanks for any insight.

Has anyone succesfully setup, and used CentOS as an iSCSI server? I'm trying to setup a server with 4x500GB HDD's, setup in RAID 10 to act as an iSCSI server for a virtualization project, but I can't find a decent howto on how to setup an iSCSI server using CentOS. I would like to setup something like Openfiler, but we also need todo some other stuff that OpenFiler doesn't

Are there any ways to improve/manage the speed of pvmove? Man doesn't show any documented switches for priority scheduling. Iostat shows the system way underutilized even though the lv whose pe's are being migrated is continuously being written (slowly) to. Thanks! jlc

Hi all, Can anyone please tell me, from experience, if it's possible to upgrade the hard drives in a RAID 10 system from 250GB HDD's to 500GB / 750GB HDD's, while the server is running? The server runs CentOS 5.5 x64. Our hardware vendors simply always say no, so we never actually tried doing this, and when a client needed an upgrade like this we had to build a new server with the

I''m planning on setting up an NFS server for our ESXi hosts and plan on using a virtualized Solaris or Nexenta host to serve ZFS over NFS. The storage I have available is provided by Equallogic boxes over 10Gbe iSCSI. I am trying to figure out the best way to provide both performance and resiliency given the Equallogic provides the redundancy. Since I am hoping to provide a 2TB

Hi all, I'm looking for a (preferably free) alternative to SME / Clark Connect. I basically need the following: - firewall - nat - VPN - bandwidth limiting / monitoring - email (SMTP / POP3 / IMAP) & groupware - file & printer sharing - RAID support - if possible fail-over / high availability support. I need to support about 15 - 30 (some part time) students, so I would like to keep

Hi all, As part of my raid experience, I have yet to have to do this, but was wondering how you guys would attempt it. I have 3 drives in a raid 1, with one as a hot spare. They are 250gb with all space used by two raid devices, 1 with boot, the other with LVMs filling them up. Now, lets say down the road I want to put in 500gb drives and replace them....yikes. I was thinking of taking out the

Hi all :) I''ve been wanting to make the switch from XFS over RAID5 to ZFS/RAIDZ2 for some time now, ever since I read about ZFS the first time. Absolutely amazing beast! I''ve built my own little hobby server at home and have a boatload of disks in different sizes that I''ve been using together to build a RAID5 array on Linux using mdadm in two layers; first layer is

Hi Everyone, I started a social networking site and I am getting ready to go live next week. I have limited fund as I am not funded yet (although hopefully soon). I have an extra Mac Pro (I know, how can I possibly call a Mac Pro dual 2.8 quad core with 16gb RAM extra). So Mac Pro quad Core, 16gb RAM, 4 x 1tb RAID level Seagate drives. I was going to load CentOS 5.4 on it, web, mysql

I have a workstation with two separate drives set up with LVM. I'm buying an LSI RAID controller to set up mirrored drives. I'd like to clone the existing drives over to the new mirrored drives somehow, but not sure the best way to do it. The original drives & their respective replacements are all identical in size (250GB + 1TB). I thought about using Clonezilla but wasn't sure
