I am trying to upgrade my system from 500GB drives to 1TB. I was able to partition and sync the raid devices, but I cannot get the new drive to boot. This is an old system with only IDE ports. There is an added Highpoint raid card which is used only for the two extra IDE ports. I have upgraded it with a 1TB SATA drive and an IDE-SATA adapter. I did not have any problems with the system

I'm going to guess that there are no IDE drives that have 4096 byte physical sectors, but it's worth confirming you don't have such a drive because the current partition scheme you've posted would be sub-optimal if it does have 4096

I have a 500GB Sata drive about 15% used I would like to make an exact copy of too another Sata 500GB drive as a spare. That way if something happens to the one in service I can plug in the spare quickly and restore one of the weekly backups without reinstalling the entire OS and all the little tweaks of setup on this mail/web server. How do I do this? That is make an exact bootable copy of a

Hello, I was wondering if someone could help me, I'm putting together a Server for personal use, I want to virtualize a few servers(mail, web, ssh) and use it as a NAS, but I have a question if I can use Multiple RAID Arrays using the following HW: Intel Xeon Quad Core X3430 ASUS P7F-M LGA 1156 - LSI MegaRAID(integrated) - HighPoint RocketRAID 2640x1 2 Hitachi 500GB HDDs 4 Hitachi 1TB HDDs

Hi Everyone, I am stack between two identical systems (2U Twin2, 4 nodes, SuperMicro) servers that have the same exact specs except for HDDs. These nodes will all either have Asterisk installed with CentOS or will have Asterisk install in virtual environment. Option 1: *12* x 3.5" HDD (3 HDDs per node) Option 2: *24* x 2.5" HDD (6 HDDs per node) **both options come to the same price.

My take is that unless you have loads of data and are trying to optimize for cost/TB, HDDs are probably not the right choice. This is particularly true for random I/O workloads for which HDDs are really quite bad. I'd recommend a recent gluster release, and some tuning because the default settings are not optimized for performance. Some options to consider: client.event-threads

Hello, Not sure where to start looking, so I start with the program that threw the message. Not sure what information I need to provide or the preferred formatting. I did a BIOS update and now get an error message I never saw before. System seems to boot ok, run programs ok, access devices ok (SATA DVD, IDE HDD, SATA HDD, network, video, audio, USB, IEEE1394). But I don't think Linux

I would go with at least 4 HDDs per host in RAID 10. Then focus on network performance where bottleneck usualy is for gluster.

Hello all Nill experience with LVM. Have a Default Centos 4.4 install updated till a week ago with three HDDs. System's not booting up since my staff pulled out the plug due to a short circuit nearby. Machine is a PIII 550 MHz, with 3 HDDs 40 GB, 120 GB (Actually is bigger but my bios detects only upto 120 GB) & 20 GB...about half filled with data & the backup server taken out in

Hello, i have some questions about the new dovecot replication and mdbox format. my company has currently 3 old dovecot 2.0.x fileserver/backend with ca. 120k mailboxes and ca. 6 TB data used. They are synchronised per drbd/corosync. Each fileserver/backend have ca. 40k mailboxes im Maildir format. Our MX server is delivering ca. 30 GB new mails per day. Two IMAP proxy server get the
