View 9 Replies View RelatedUbuntu :: All Disks Spin Up Every 10 Hours / How Do I Find Culprit?
Jul 10, 2011I'm running 10.10 with about 10 SATA disks attached. If I spin them down with hdparm -Y, every disk that has a filesystem on it (but -not- disks that are partitioned but have no filesystem) spin up, simultaneously, about every 10 hours. How do I find the culprit? The machine is sitting effectively idle---I know it's not something I'm doing that's causing the spinups.Is there some way to monitor -anything- that touches a particular block device?
My suspicion is that this might be the gnome low-disk-space warning daemon statting everything. (This -used- to be gnome-volume-manager, but I'm not sure where that code went when GVM was dropped in 10.10---how do I find that code? What package is it in?)
And if it -is- the disk-space monitor, how do I kill it dead? Not just "don't tell me about disks", but "don't even bother looking". I would -really- like these drives to spin down and -stay- down, possibly for days or weeks, until needed---not spin up every 10 hours until I either manually spin them down or until whatever I've set in hdparm spins them back down.

Feb 25, 2010I have servers which contain SATA disks and SAS disks. I was testing the speed of writing on these servers and I recognized that SAS 10.000 disks much more slowly than the SATA 7200. What do you think about this slowness? What are the reasons of this slowness?
I am giving the below rates (values) which I took from my test (from my comparisons between SAS 10.000 and SATA 7200);

Ubuntu Installation :: Which Disks Can Be Main Boot Disks
Mar 31, 2010I have/had a PC with several hard drives, and a mix of ubuntu and windows on multi boot.The old boot drive died screaming, and I need to start again. (But my data is safe! yay!)
Is there anything special about which drive can be the main drive to start booting from? Or to put it another way, can I install to any of the other 3 and expect it to work, or do I need to switch them around so a different drive is on the connections for the recently dead one?

Ubuntu Installation :: XP With Existing Setup (Partitions) - Error "Setup Did Not Find Any Hard Disks Installed On Your Computer"
Feb 18, 2010I'm using Ubuntu 9.10 and previously had a separate partition with another distro on it. I decided to delete the other distro's home and swap partitions and install XP in place of it. I've been following these instructions: [URL] and [URL] I have gotten to the point where I am booting to the XP CD and want to install it, but I get the message, "Setup did not find any hard disks installed on your computer" when I should be getting to the screen that asks me to select a partition to install XP on. This is what my HDD looks like in GParted:
I want to install XP in the unallocated partition, but I have a feeling I screwed up somewhere along the way and probably don't fully understand the whole thing. Even if I try to format the unallocated partition to NTFS I can't make it a primary partition (I assume because it's within sda2). The very last thing I want to do is delete my Ubuntu partition and start from scratch, but if that's my last option let me know.

Jan 13, 2011I recently followed this guide to create a RAID1 [URL]... First I partitioned the disks with fdisk. I made the RAID array with
mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sdb1 /dev/sdc1. Then I created the filesystem with mkfs.ext3 /dev/md0.
I then mounted md0 at /Video with mount /dev/md0 /Video/ All according to the guide.. Today I made a samba-share out of /Video/Rorschach to easily put files in there from my windows7-machine (the plan is to steam from my CentOS-server to my HTPC which hasn't arrived yet). I started to put movies in there. It went just fine for a while but then I got this message: [URL]... How is that even possible when df -h looks like this?:

View 5 Replies View RelatedGeneral :: External Hard Disks
Mar 22, 2010I'm using SUSE11.1, and connected to my system, a DELL 7500, a 1.5 TB Buffalo external HD. I partitioned it in 4 sectors.After connection, nmediatly the mounted disk would appear on the screen,(each partition with its respective name), and could use it as any other folder.To unmount the external Hard disk, I just ejected each partition, and had no problem. I used the same HD with my Mc, and things were all right, I used to backup automatically the Mc. However after having been using the system in this way for more than half a year, suddenly the hard disk began to rattle...and the SUSE system on the DELL, nor the Mc can mount the external hard disk any more. Thus, the partitions can not be mounted any more. When I cd to /media/ in the SUSE, the names of the partitions appear, but they seem to be empty..On the Mc, going to /Volumes/, before the problem appeared, the names of the partitions were there... but now, they are no more and the automatic back up either.So my question is, how to mount the disk, if it needs mounting... or how I can recover the partitions and the data therein... I am clueless, after two weeks trying to solve the problem..

General :: Using Mersenne Twister To Wipe Disks?
Jan 28, 2011Currently when I want to wipe a USB disk with pseudorandom data in Linux I do the following:
dd if=/dev/urandom of=/dev/sdb conv=notrunc
urandom is very, very slow, it gets to the point where the bottleneck is not the device. I know of another method -- the Mersenne twister. This is used in one instance by DBAN as a PRNG to securely erase data with, and it is easily 'random' enough for wiping drives -- and it is very fast. However, I'm not sure how I would use it in Linux. Is there a Mersenne twister program which I can then pipe into dd to wipe drives with?
General :: Restore Data From A Set Of Old LVM Disks Using Images?
Aug 6, 2011I have three hard drives that were previously in a Debian server setup to use LVM that I now need to access data on. The first hard drive had a boot partition along with an LVM partition, the other two hard drives were also LVM.From what I remember I have to mount all three at once for LVM to function correctly but I don't have available hardware (particularly a motherboard that can mount all old IDE).Can I use a USB<->IDE converter to image the disks, and then mount them?What Linux distro should I set up to recover the data?ow do I know what version of LVM is needed?

View 4 Replies View RelatedGeneral :: Using LILO Then Moving Hard Disks Around
Jun 15, 2010A few years ago I built a small Slackware system and, for storage, I used using a 2Gb Compact Flash card plugged into the primary IDE interface. Initially, I made a bootable CD rom, booted the new system from that, copied the file system to the CF card and then ran LILO to install a boot sector on the CF 'disk' /dev/hda. That all worked well enough.
The only trouble is that the CF card, being an early one, is rather slow and so I've just bought an Innodisk 2Gb Disk-on-Module which ought to be much faster. I have plugged that into the secondary IDE interface, I've run cfdisk to make a partition, formatted it using mkreiserfs and copied all of the contents of the CF card on /dev/hda to the new device on /dev/hdc. So far, so good. But...Now I need to run LILO from the existing CF card in /dev/hda to put a boot sector on the new /dev/hdc. Then I want to move the new device from /dev/hdc and put it in /dev/hda once it's bootable.
I'm stuck to know how to configure LILO to install a new boot sector on /dev/hdc. I don't appear to be able to make LILO understand what I'm trying to do. If I change the line 'boot = /dev/hda' in lilo.conf to 'boot = /dev/hdc', LILO aborts with an error message.

General :: Using A Flash Drive To Speed Up Conventional Disks?
Jun 12, 2010Is there a possibility to use a flash drive as a speed up for conventional hard disks? I got the idea to redirect all read ops to the flash drive if the data is already stored there, and to read from the conventional disks if the data is not found there (and during idle time the freshly accessed data from the conventional disk is stored on the flash disk).
Is this already possible with linux standard tools?
General :: Untouchable Disks Via Disk Utility And GParted

What can I do?

View 1 Replies View RelatedGeneral :: 2 Disks Failed Simultaneously On A RAID 5 Array?
Apr 15, 2011I have a home server running Openfiler 2.3 x64 with 4x1.5TB software RAID 5 array (more details on the hardware and OS later). All was working well for two years until several weeks ago, the array failed with two faulty disks at the same time. Well, those thing could happen, especially if one is using desktop-grade disks instead of enterprise-grade ones (way too expensive for a home server). Since is was most likely a false positive, I've reassembled the array:
Code:
# mdadm --assemble --force /dev/md0 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1
mdadm: forcing event count in /dev/sdb1(0) from 110 upto 122
mdadm: forcing event count in /dev/sdc1(1) from 110 upto 122
[code]....
Right. Once is just a coincident but twice in such a sort period of time means that something is wrong. I've reassembled the array and again, all the files were intact. But now was the time to think seriously about backing up my array, so I've ordered a 2TB external disk and in the meantime kept the server off. When I got the external drive, I hooked it up to my Windows desktop, turned on the server and started copying the files. After about 10 minutes two drives failed again. I've reassembled, rebooted and started copying again, but after a few MBs, the copy process reported a problem - the files were unavailable. A few retried and the process resumed, but a few MBs later it had to stop again, for the same reason. Several more stops like those and two disks failed again. Looking at the /var/log/messages file, I found a lot of error like these:
