Red Hat / Fedora :: Smartd For IBM RAID Server(redhat)?
Aug 13, 2010
I am using smartd for monitoring disk's status and i am using smartmontools-5.39.1.tar.gz package for compilation. I am able to compile and run it on HP servers(redhat). Now,i need to execute it for IBM RAID SERVERS too on which compilation is done but i need to configure smartd.conf for them so as to monitor all existing disks. (only DEVICESCAN works in conf file). Rest devices to monitor(eg. ata, sda devices) don't work at all. it is possible in IBM raid servers and if yes, then what configurations should i use.

I'm having some trouble understanding the smartd configuration options which go in /etc/smartd.conf. I've had smartd running for close to a year now, and read the manual page for smartd and smartd.conf several times, and I still can't get my head around it properly. This is what I use in smartd.conf:
/dev/sda -H -f -S on -o on -n standby,q
-s (O/../.././(00|06|12|18)|S/../.././11|L/../../(3|6)/21)
-m <nomailer> -M exec /usr/sbin/smartd_mailer
The above works fine (I use a custom script because I use exim). However, I had two failing hard-disks on two different machines (sector pending attribute) - but I would only receive warning emails if I restarted the machines - not when the periodic tests were being performed. I have a number of questions, if any of you would like to share some light on this:
1. It is not clear from the manual page how the monitoring and alerting mode works. Do I get an initial email when I start smartd if something is wrong, and then no other warning email after each scan, even if there is a fault, unless the fault goes worse?
2. Can I force it to send me warning emails after each test (offline, online, short, long etc.) if the fault condition is still there, even if it hasn't gotten worse?
3. There seem to be a variety of parameters monitored. I was thinking that if I monitor bad sectors, and the hdd temperature - it should be enough to warn me when the hard-disk is failing? Would the -a switch in smartd.conf cover these?
4. I don't understand the difference between monitoring and logging in relation to alerts? Do I get alerts only if I log things?
5. Do I understand correctly that the -p and -u switch would warn me of *any* changes in SMART attributes, even if they don't represent risk of failure?
6. Is there a way of finding out if the scheduled tests (offline, long, short etc.) have been performed?

I have just joined this respective forum and I have a issue with website hosted on Virtual Redhat Server. Scenario is like this I have three virtual redhat server(R1,R2,R3) 5.0 on VMware workstation 7.0 installed on window 7(physical machine), on R1 I have DNS server , On R2 I have Apache web server and I have hosted a website called "geekgadget.com" just for testing purpose, R3 is just a normal server nothing installed on it yet..
Problem : I can access my website [URL] from all of my three virtual redhat server but when I try to access it from some of my physical XP,window 7 machines as well as from virtual XP machine present on my local LAN, website cannot be accessed so I am not getting the point why it happens because I checked that my port 80 is listening.

I am trying to connect a RAID Box to the server via LSI 8880EM2 RAID controller.The raid box is FUjitsu Externus DX60 with raid 1 configured.The server is Fujitsu Primergy SX300 S5 with LSI 8880EM2 RAID card.The external raid box is being recognised by the raid controllers bios.
The server runs CentOS 5.5 64bit. I have installed the megaraid_sas driver from LSI website and MegaCLI utility but CentOS still fails to see the box.MegaCLI utility, when launched from CentOS, recognises the raid box, CentOS does not(no mapping being created in /dev).
I have also tried to create a logical RAID0 HDD on one physical HDD(as seen by MegaCLI) with MegaCLI utility in CentOS.The result was success and the new logical drive could have been used, but when restarting the server, the controllers' bios fails with an error (not surprised(one logical RAID0 on one physical HDD)) and configuration is being erased.
Has anyone tried connecting 8880EM2 controller to a raid box with raid configured on the box, running it all under CentOS and what were the results.

I've tried to install Fedora 11, both 32 and 64 on my main machine.It could not install as it stops on the first install window. I've already filed a bug but really haven't seen any feed back yet.The bug has something to do with Anaconda and the Raid array but I really can't tell.
I have an Intel Board (see signature). I am running intel raid software under W7 currently.It works fine. But, I'm wondering, when I attempt to install F!!, is my current raid set-up causing problems? Do I need to get rid of the intel raid software and use a Fedor/Linux raid program to manage the raid array??

Right now i have a HP DL 180 Server with 130 Gb Hard Disk & 8 Gb ram after Raiding0+1. i want to configure Domain Controller Server for my office for 200 to 300 Users. what should the partition size must be mentioned in my 130 Gb Hard Disk, is that going to be Sufficient for ME ?
i am bit confused about /Usr /Var /Boot partitions, as i need to manage perfectly in 130 GB
if i go with 4 Gb swap and remaining for " / " is that will be fine ? should i need to specify partition sizes separately for / tmp /var / usr ..

I have had no problem installing Fedora OS on any of my Dell servers prior to this post. Anyway, I wouldn't call this a problem but recently, we bought another DELL server with Quad Core, 4GB, etc... AND this model has 2 swappable SAS Harddrives.
I wouldn't call myself an expert but then again I am not a newbie too. However, I have never setup any RAID before and now I am forced to setup RAID1 on this server. So, in a way, I am a newbie in setting up RAID
Would someone please point me in the right direction as I have no idea what I am supposed to do to setup the RAID. FYI, I will be installing Fedora 10 64bit on this server. I would appreciate if you can start from the very beginning, ie. partitioning, formatting the harddrives during OS installation, etc..

I am trying to share a couple of resources from my fedora 12 box to a windows vista, using samba. It seems absolutely fine to share any folder but as soon as I am trying to share a folder which is used as a mount point windows cannot access this folder. I get the following message from windows:"the network cannot be found". This must be due to some permission, but I cannot find which one.
Note that windows can access the folder but as soon as the device is mounted I v#can see the folder in windows but cannot access it. Here is a copy of the smb.config file:
[global]
workgroup = workgroup
server string = GAIA
security = share
;guest account = nobody
[Code]...
Note that I have been trying to execute the same with mounting and sharing a raid1, but windows cannot see it.

I am running OpenSUSE 11.2 (but I do not suspect that this is distribution-specific).Linux bach 2.6.31.8-0.1-desktop #1 SMP PREEMPT 2009-12-15 23:55:40 +0100 i686 i686 i386 GNU/Linux.I am running in runlevel 3 while trying to sort this out.When smartd runs, it spins up my Western Digital drives from standby, but not my Samsung drive.Anyone know why blkid, edd_id and devkit-disks-pa are reading my standby drives? And are these reads sufficient to make drives spin up? I'm not sure what to look at next.

I'm attempting to install F13 on a server that has a 2-disk RAID setup in the BIOS. When I get to the screen where I select what drive to install on, there are no drives listed. The hard drives were completely formatted before starting the 13 installation. Do I need to put something on them before Fedora will install?

I am looking to convert a raid 1 server I have to raid 10. It is using software raid, currently I have 3 drives in raid 1. Is it possible to boot into centos rescue, stop the raid 1 array. Then create the raid 10 with 4 drives, 3 of which still has the raid 1 metadata, will mdadm be able to figure it out and resync properly keeping my data? or is there a better way to do it?

I have a box that doesn't have a Raid controller or a software raid running currently. I would like to make it a RAID 1. Since it seems there isn't any IDE RAID controllers hardly around, I have another HD that is the exact model as the drive currently in the box running CentOS. Can I some how add the second drive and get the box to mirror from here own out? The box gets really hot and I want to be ready for a HD failure.

I recently installed two 160Gb hdds, and use these with striped LVM technics.
now I came across /var/log/messages these lines... :-/
Feb 14 16:50:44 centos55 smartd[4826]: Device: /dev/sdf, 34 Offline uncorrectable sectors
Feb 14 16:50:44 centos55 smartd[4826]: Device: /dev/sdg, 14 Offline uncorrectable sectors
To my understanding, this means that the disk is beginning to fail, and should be replaced..
Short story..I have about 35.000 images on these disks... (shared on network, as a samba share with PCs using Picasa) I've doing backup to 2 separate USB disk, and sometimes I connect a third usb disk and transfer to this aswell. I'm worried now that "some" of my image/data might have been lost - due to the 2 lines above. (checking if something is missing, of the 35.000 images is not easy.. and I have not made any txt file with all files/names/size og the images -...I see now that I also should create such a list, and not just take backup)
How critical is this "Offline uncorrectable sectors" and how can I check/do something about it ?

I'm looking to set up a server with attached mass storage device and tape autoloader to run linux. It's set up under Windows at the moment. Goal is to have users, connecting from individual workstations and laptops, backup their data to the linux server. On their personal machine, some users run linux, some MacOS, some Windows. I plan to set up the 5 500 GB drives as RAID5. I understand that if setting up as software raid the format is "physical volume for RAID". Under this setup, will Windows users be able to read/write and function as expected? I can't assume only linux user access.

I'm trying to rsync files and directories from a RedHat linux host(v 4.5 & 4.7) to a Windows server 2003R2 Standard Edition with cygwin running. I'm executing the rsync command from the cygwin shell. The transfer involves rsync'ing approximately 1 TB of data from the linux server to the windows server. After about 280+GB of data transfer, the transfer just dies.
There seems to be no particular file or directory that the transfer stops at. I'm able to rsync GB's of data from other linux hosts to this cygwin server with no problem. Files and directories rsync fine.The network infrastructure is essentially the same regardless of the server being rsync'ed in that it is GB Ethernet running through Cisco GB switches. There appear to be no glitches or hiccups across the network path.
I've asked the folks at rsync.samba.org if they know of any problems or issues. Their response has been neutral in that if the version of rsync that cygwin has ported is within standards then there is no rsync reason this problem should happen.I've asked the cygwin support site if they know of any issues and they have yet to reply. So, my question is whether the version of rsync that is ported to cygwin is standard. If so, is there any reason cygwin & rsync keep failing like this?
I've asked the local rsync on linux guru's and they can't see any reason this should fail from a linux perspective. Apparently I am our company cygwin knowledge base by default.

2 months ago, I built a dedicated backup server using 4 2TB SATA drives for software RAID5 (6TB total). A few days ago, smartd sent out mail saying it found an unreadable sector on one of the drives. I ran selftest using smartctl and the error persisted. So far, neither software RAID nor ext4fs running on top of the RAID volume have reported errors.
MOST OPTIMISTIC: It is normal to have a few bad sectors among billions. Software RAID takes care of alternatives. Keep using the system until RAID spits a more serious warning in the future.
MOST PESSIMISTIC: It is a really bad sign to lead a disaster. No good disk drive should have bad sectors especially when it is only 2 months old. The error is simply not detected by software RAID and ext4. Replace the drive immediately and return the bad drive to the supplier.

Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
I was able to examine the disks though:
Code:
root@127.0.0.1:/etc# mdadm --examine /dev/sdb2
/dev/sdb2:
Magic : a92b4efc
Version : 00.90.00
code....
Code:
mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.
