similar to: RAID hard drive serial numbers?

I'm looking for RAID options for at least 10 TB to attach to a Dell PowerEdge 2950 running RHEL 5 64-bit Server. The system will act as a single sign-on server for XP and Linux, thus storing user's data from mounted home directories exported from the server to various workstations. It may also house a database. I'll need a storage solution starting at least 10 TB. Most of the

It recently occurred to me, as I was partitioning a RAID with fdisk, that when I built the system, I was presented with a graphical utility that "magically" created the partitions. Now, using fdisk, I was reminded of being given superblocks. Although I haven't used data recovery techniques using superblocks, is there a way to retrieve the superblock numbers the OS has assigned

I have a RHEL5 Server and some dual-boot XP/CentOS 5 systems (Linux systems all 64-bit). All Linux is out-of-box, with all packages, minus international languages, installed. No patching has been done. On the server, I selected system-config-authentication and enabled LDAP for User Information, Kerberos, LDAP, and SMB for Authentication, and Shadow and MD5 Passwords, along with

Hi, The server is running CentOS 5.8 Linux OS on Dell PowerEdge R710 having raid controller card 03:00.0 RAID bus controller: LSI Logic /Symbios Logic MegaRAID SAS 2108 [Liberator] (rev 05) /usr/sbin/smartctl -a /dev/sda smartctl version 5.38 [x86_64-redhat-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ Device: DELL PERC H700 Version: 2.10 DELL

I have a Dell PowerEdge 2950 with PERC 5/i, and 6 disks. Two disks have one logical volume via a hardware RAID 1 and consist of CentOS 5 64-bit; the remaining four comprise a logical volume via a hardware RAID 0, and is all user data. One drive on the RAID 0 went bad. I removed it while the system was on, tried a reboot, and the system hangs at RedHat Linux... Starting I tried to boot

Though quiet at the moment, my desktop sometimes sometimes makes a noise that I attribute to either a disk or a fan on its last legs. I'm looking for suggestions for distinguishing. For the disk, I expect I should use either hdparm of fsck. Even after reading the man page, I'm not sure how I would use hdparm. If I use fsck, what should I take as evidence of a bad drive? A good drive? Is

I have a Dell PowerEdge 2950 with 6 SAS disks and a PERC 5/i controller what won't do RAID 6. I plan to have 2 drives as RAID 1 for the OS, and the remaining 4 as RAID 6. Granted the PERC can do RAID 1, I'm tempted to do everything via software RAID. Thus, if anything goes wrong with the controller, I just need to obtain a new SAS controller and I'm back up. I learned my lesson

If you have a RAID5 array, then you have one volume spread across the physical disks.? You can then

I'd like to to put the hard drives in standby mode during periods of no activity. I'm just running a file server plus a couple small things on a Qube 3 from home, although the web stuff will increase it's still minimal. On my NetBSD systems I can use atactl to do this via: mount -u -o async,noatime,nodevmtime / mount -u -o async,noatime /usr atactl wd0 setidle 5 [wait a time]

Is there a way to see what repo sites were used by yum? I want to check that my local repos are actually being used.

I believe I've posted before about one of the speed issues we were having, of backups taking many, many hours that should *not* take that long. My manager and I finally nailed it down to the h/d itself. Identical boxes, and he tried a backup of one system which took under two hours, while the same regular one rand nearly six. I'd been googling on and off for weeks, and this morning, ran

How can I tell wich HDD to swap, when the "cat /proc/mdstat" says one HDD of the RAID1 array has died? Does the HDD's has some serial numbers, that I can see in "reality", and I can get that number from e.g.: a commands output? How could I know wich HDD to swap in e.g.: a RAID1 array? thank you -------------- next part -------------- An HTML attachment

we have several R900 servers with PERC 6/E card in it. Recently it we getting some message on /var/log/message say change to "write back" and change back to "write through". We figure out it is PERC 6/E card battery weak. My questions are: 1. some battery only use one year (some even shorter) and already this problem. 2. How come PERC 5/E does not have this issue? 3.

I would like to change a few things in CUPS, but I would prefer to use the source for the version of CUPS that I already have installed using yum. Mostly because I'm quite happy with the way it works except a few details. Is there a way to get the source using yum or should I go to http://www.cups.org/software.php and get it from there ? The version I installed with yum is 1.1.22 and on
