similar to: Steps to create a mirrored CentOS system?

Saw a trick today, wondering if anybody else had done/tried this? Assume you have a 1U rackmount with 4 front-accessed drive bays, and you want all four bays for a 4-disk RAID5 storage. The idea is to use an internal USB adapter and a couple of bigger USB thumb drives to install to, RAID 1 style, freeing up all your external drive bays. At first, I didn't think that a thumb drive would

Since good server designs have come up in the past, I wanted to point out a "low-cost" server option that has good I/O, and the vendor offers _your_choice_ of not only Fedora Core or Red Hat Enterprise Linux, but _also_ CentOS _shipped_ with it! IN-A-NUTSHELL ... Starting at just over $750, you can get a single Socket-939 Opteron 1xx (dual-core is an option) system with up to 4GiB of

I have a 750Gb 3-member software raid1 where 2 partitions are always present and the third is regularly rotated and re-synced (SATA disks in hot-swap bays). The timing of the resync seems to be extremely variable recently, taking anywhere from 3 to 10 hours even if the partition is unmounted and the drives aren't doing anything else and regardless of what I echo into

Hi all, Helping a friend setup a new machine - it will be a low volume web and mail server. He wants to set it up with 2 drives in a mirror setup. The motherboard he bought supports mirroring on the hardware level. I have heard of issues before using hardware raid on Linux systems. Which way would you recommend we go on this? Thanks for any suggestions. Dale

Hi, I know (from the zfs-discuss archives and other places [1,2,3,4]) that a lot of people are looking to use zfs as a storage server in the 10-100TB range. I''m in the same boat, but I''ve found that hardware choice is the biggest issue. I''m struggling to find something which will work nicely under solaris and which meets my expectations in terms of hardware.

Hello All, I build a new Storage Server to backup my data, keep archives of client files, etc I recently had a near loss of important items. So I built a 16 SATA bay enclosure (16 hot swappable + 3 internal) enclosure, 2 x 3Ware 8 port RAID cards, 8gb RAM, dual AMD Opertron. I have a 1tb boot drive and I put in 8 x 1.5tb Seagate 7200 drives. In the future I want to fill the other 8 SATA bays

Greetings, on this matter, Sunfire x4150 a 1U machine with 2xcpu sockets, "eight" drive bays, 64 GB expandability, 4 NIC packs quite a punch for its size. I don't think I've ever seen such power in such a small package Regards Rajagopal

I have found a: HPE 873830-S01 ProLiant MicroServer Gen10 for <$300 without drives.? If I can believe the seller, it has a AMD Opteron X3216 Dual-core (2 Core) 1.6GHz and 8GB Installed. It has 4 3.5" bays. and 1? "Media" bay? https://www.servertechsupply.com/873830-s01/ this could well be acceptable.? Got to find out power draw.? Looks like ~40W. Any input on issues of OS

I''ve have a single-fs, mirrored pool on my hands which recently went through a bout of corruption. I''ve managed to clean up a good bit of it but it appears that I''m left with some directories which have bad refcounts. For example, I have what should be an empty directory "foo" which, when you cd into it and ls -al, it shows a incorrect refcount for a empty

My current home fileserver (running Open Solaris 111b and ZFS) has an ASUS M2N-SLI DELUXE motherboard. This has 6 SATA connections, which are currently all in use (mirrored pair of 80GB for system zfs pool, two mirrors of 400GB both in my data pool). I''ve got two more hot-swap drive bays. And I''m getting up towards 90% full on the data pool. So, it''s time to expand,

Hi all, Some how I have an extra active route setup in my CentOS 4.4 system (that unfortunately at a data center a ways away from me). I have tried using /sbin/route del -net xxx.xxx.xxx.xxx but get an error. I also have Webmin installed and I can delete the route from there, but on applying the network config, the route comes back. I have no idea where it is coming from. It is preventing me

I've mentioned this problem before but put off doing anything about it and maybe now someone can suggest the best solution. I have a 3-member RAID1 set where one of the members is periodically swapped and rotated offsite. The filesystem contains a backuppc archive which has millions of hardlinks that make it impractical to copy with a file-oriented approach. The current filesystem is

Arch = x86_64 CentOS-6.4 We have a cold server with 32Gb RAM and 8 x 3TB SATA drives mounted in hotswap cells. The intended purpose of this system is as an ERP application and DBMS host. The ERP application will likely eventually have web access but at the moment only dedicated client applications can connect to it. I am researching how to best set this system up for use as a production host

I'm following the Debian wiki at https://wiki.debian.org/AuthenticatingLinuxWithActiveDirectory since it seems to be the only one I can find and since I'm running Debian/Bookworm on an AMD64 system. I'm in the section "Configure Kerberos" which is near the start. My /etc/krb5.con file (with most comments removed) is: > # cat /etc/krb5.conf > [logging] >

Hello all, I have a DL360 G4 1U server that does a wonderfull job with dovecot horde, Xmail and OpenLDAP for a company and serving about 40 acouunts. The machine is wonderful. I am very happy with it. However, I am running out of disk space. It has two times 76Gb Drives in RAID1 (disk mirroring) and the capacity has reached 82%.? I am starting of getting nervous. Does anyone know of a painless

Hello all, I am thinking about a new laptop. I see that there are a number of higher-performance models (incidenatlly, they are also marketed as "gamer" ones) which offer two SATA 2.5" bays and an SD flash card slot. Vendors usually position the two-HDD bay part as either "get lots of capacity with RAID0 over two HDDs, or get some capacity and some performance by mixing one

I had an old server die; we had another, same model, sitting around lightly used, so I did what I've done before: swap the RAID card into that, swap the drives, even putting them in the same bays as the dead one, and boot. Nope. 100% of the time, when it hits switching roots, it kernel panics. Adding rdshell to the kernel line does nothing, I get no grub rdshell. Booting from a flash
