A hard disk occasionally fails. Standard checks like fsck and scandisk fail to report any problem. Is there other software to exercise the disk much more thoroughly so that bad sectors have no chance of being missed?

View 2 Replies View RelatedI did set up a new server (with mail, apache and lots of other stuff) and was not aware that the new harddisks of type WD10EARS-00Y5B1 were using 4KB sectors internally. The problem became visible after going live because of the lousy performance of the harddisk drives.
Present situation: openSUSE 11.2 i586, 4 GB RAM, 2x 1TB HDD
Code:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000efdd0

I already did re-partition /dev/sdb with parted-2.2 (compiled from source) and set the alignment starting with sector 64 (instead of the default 63) making sure that the sector count of every partition divides by 8. Now comes the tricky part: I must partition /dev/sda as well. I can backup everything to /dev/sdb. What is the recommended course of action here? Make sdb active and boot it? That would give me all the time I need to deal with sda. Then reverse again. Any backup of /dev/sda will be outdated soon (running system)Rescue DVD only offers parted-1.9.0

I've just tested my new (actually old as hardware) nodes in computing cluster. Use for this http://systester.sourceforge.net/. But in params for tester above 32M system refuses to allocate memory in spite of there are about 250M free.It's because it too defragmented so i cannot run such tester. In future actually will be tasks with big linear memory queries, so is it possible to defrag RAM after every system loading?For this moment can you also point out for me other testers weith big memory queries but without linear manner?

I have a Red Hat Enterprise Linux 4 server on my network & that I inherited with no documentation what so ever and it has an application called 'Clearquest' installed from IBM. This application uses some proprietary web server that gets installed with the 'Clearquest' application. My problem is I need to find the SSL certificate the web server is using. If this were Apache, I would look in '/etc/httpd/conf.d/http.conf' but there is no Apache software installed. Can someone please assist me in a way I can look through the RHEL 4 server for any trace of the SSL certificate. I don't know the actual name of the certificate but I know the server is rendering it on the web. When I type the address of my server in the URL field, I can see the servers SSL certificate. Now how I can find that certificate path / location on the server itself?
View 1 Replies View RelatedI'm trying to install Ubuntu Server on a test server at work. So I downloaded the .ISO from Ubuntu's website and burned it to a CD using InfraRecorder at 12x. It booted fine, but it failed a disk integrity check.
Tried to check the md5 of the ISO by mounting it vCdControlTool (I'm running Windows XP Pro on my workstation) and opening the md5sum file... and it was huge! Like 128 lines huge... I tried using md5summer (and later md5 check) to check it anyway and it returned a bunch of errors. So i redownloaded the ISO and burned a new disc. Same error.
Now I'm pretty sure I'm not doing the md5 check right, but either way I've downloaded the ISO twice and burned three copies now and all have given me the same error.

View 6 Replies View RelatedI am a total noob in the process of trying to build my own server. I installed Ubuntu 10.10 but when I did that I didn't have the computer hooked up with an ethernet or have any internet connection. During the installation process it was unable to set up DHCP, so I figured I would just do that later, somehow.
Anyways, I recently hooked up an ethernet cable from the server to another computer, which has internet.
I've been slowly working my way through the Server Documentation and am on the Networking chapter. It has given me the commands to install wireless-tools, ethtool, dhcp3 server and I've also tried to install gedit. Every time it gives me the error: E: Unable to locate package XXX
When I ran the sudo lshw -class network command I find that it recognizes both an ethernet interface as well as a wireless interface(my wireless adapter). BOTH of them say *-network DISABLED.
My goal is to enable both of those, but I am assuming I need to be able to locate the packages first. I installed the server edition using a USB pendrive. I still have the files on the pendrive, but I don't know how to make the server locate those files. I'm guessing it wants to access the installation files to locate the packages to install.
does anyone know how can I use locate with rm? rm `locate "some file"` does not work when my pathnames occasionally contain:
-spaces and other characters (like + or possibly others that need escaping)
-greek characters
how can I grab line-by-line the output from locate and wrap quotes"" around the paths?
Im still a newbie in Linux. I would like to know how to burn an ISO image to DVD using RHLServer.

View 1 Replies View RelatedI have some errors on my drive and I fear it may be faulty. However there are a few things I would like to try before replacing it through the manufacture or buying a new drive of my own seeing as this is a brand new computer.
Here is my computer and drive:
Acer 5251-1513 Laptop
Toshiba MK2565GSX
Running Fedora 13...now
Here is what is going on. Tried several version of Ubuntu 10.4 (studio, 64bit, 32 bit) and was having many errors during startup and having to press F to fix. Then I lost something with Gnome and the GUI would not function, and I did not know how to replace it. Tried a few other distros but could not get them to work (mostly on my part I am sure.) Then after some forum talk, thought it might just be Ubuntu unable to handle my drive. Now on Fedora 13 and a warning comes up every time I startup. "Disk has many bad sectors"
In the disk utility under the SMART Data it has 2 of the following warnings:
5- Reallocated Sector count..with a value of 72 sectors
197 Current Pending Sector count...with a value of 35 sectors
Total Bad Sectors 108.
The next day that went up to 110
I have used Fsck several times through a live CD, but the problem persists. Trying to understand bad blocks and how to write them to a file?
I have an Acer tiny desktop using laptop components and I want to replace its small laptop hdd running Vista with a Kingston SSDNow V Series Boot Drive 30GB and install Ubuntu, since it will support TRIM. I am aware of the current issues on some new hard drives with 512 vs. 4k sector sizes and the necessity to align sectors for those drives. And I know I've seen some posts or discussion of aligning sectors for SSD's.
I'll be doing more searching for info on this, but my previous searches on the 4K sector alignment issue for the new WD hdd's on linux were confusing. Does anyone have definitive information on the necessity of aligning 4k sectors on current Linux kernels, or on whether aligning sectors is necessary for SSD's?
I recently buy a Corsair F60, and F14 (and F11) said there is MANY bad sectors on my SSD. Is it a smartctl bug ? how can I confirm or infirm that ?

After scanning selected spans, do NOT read-scan remainder of disk.If Selective self-test is pending on power-up, resume after 0 minute delay.
I have a massive ZFS array on my fileserver. Whenever a disk reports bad sectors to smartmon, I order a replacement, and I shelve the failing one.
And by "shelving the failing one", I mean that I give it a low-level format if applicable, or a destructive badblocks run to possible claim spare sectors to replace the bad ones, then use it to dump my DVDs (and lately BluRays) on, so that I can use it with my HTPC and bring it with me when going to my friends to watch movies. It's just a really easy and portable way to watch movies with XBMC. I have the stuff on pressed discs already, so I'm not dependent on their reliance, and the dying drive just gets a hospice life serving as quick-access media storage. Keeping in mind Google's reports that drives are 39x more likely to die within 60 days after their first SMART error, I'm expanding that period by the fact that these drives mostly remain on their shelves and are only plugged into the SATA bay once or twice every year.
I'm just saying this to make clear that I'm not confused about these drives dying, and I'm not looking to elongate their lives ;)
So. Sometimes these drives, after a badblocks run, simply claim fresh sectors from the spare pool, but sometimes there aren't any left, and I face the fact that there are bad sectors in my FS. That's not a problem if you use one of a set of linux filesystems, as mkfs.* often takes a badblocks list as input. But seeing as I sometimes bring a drive or two to my girlfriend's (Mac) or one of my friends (usually Windows), I've decided to use NTFS for these things. Up untill now, when a drive had unrelocatable bad sectors, I've just written data to it, re-read it, and files that were bad were put in a "BAD_SECTOR_FILES" folder on the drive.
Sure, it works, but it would be really nice to be able to just mark those sectors bad instead. It's a lot of hassle the other way around.
So I read some posts, of which most quickly switch subject to the often accurate one of "replace your drive!", and some suggest spinrite, but really, I don't see why I should pay that much money for such a trivial task.
The alternative is to use ext3, but I'd like to hear if someone knows how I can feed badblocks output to mkfs.ntfs, so that the bad blocks aren't used. Or if there are other tools (I could use Windows in a VM) that do the same. I'm confused about chkdsk, it seems the bad sectors thing is FAT only?

Then after a while windows wont even start. So I tried to use ubuntu netbook live from a usb and it is working fine ! I can even access all my data on the hard disk, although it is telling me that the hard disk is failing and that it has 1024 bad sectors. I have only one hard disk and one partition (120 GB). Can I just install ubuntu and somehow block the bad sectors? (I don't want windows anymore) and is there any way I could keep my old data on the hard disk without backing it up (it is not really important btw).

View 5 Replies View RelatedI've just added a second disk to one of my computers. It is a 500GB SATA. It is the second drive according to the BIOS. Fedora calls it /dev/sdb. So far so good. This box is running Fedora 13 final. Never any problems until the addition of the new disk. Palimpsest says that this disk has a LOT of bad sectors. This disk is a storage drive. I want to address the problem but don't know what to do first. My thought is to rsync all the data to my external 250GB disk bedore I do anything else but I'm mot sure if I should just yet. Maybe I should run some diagnostics on the drive? If so, what? How about the tools Disk Utility offers? Should I use the Smart Utilities? What other Linux tools are available and are they reliable? Maybe I should install XP on the main disk and use Windows' disk tools? If I should lose all data it wouldn't be the end of the world but I'm not sure how "in sync" the 2 storage drives actually are.
