Slackware :: Filesystems Missing From Hard Drives
May 15, 2010
This is driving me mad, so bear with me. I'm not sure this is a Slackware issue, in fact I'm sure it's not, but you all have helped me in the past so it seems like a good place to start. Also, I don't really know exactly how much of this information will be completely relevant to my problem, but I really can't pin it down.My server is running 64 bit Slackware 13. It was running fine, mainly just serving files on the LAN, with some occasional SSH activity. I was slowly moving hard drives to it from my desktop system (all 1 or 2 terabyte drives). They were previously formatted with NTFS and were filled with files, so it took me a while to move data around, format a drive, and copy the data back. I decided to use ext4, for no particular reason other than it was the newest, so if I end up having to reformat these again, I'm open to using another filesystem. Right now, I've got two 2TB drives and three 1TB drives, but one of those is still NTFS, so it is of no concern at the moment.
At this point, I had just added the two 2TB drives to the system. These happened to be the new WD Advanced Format drives with 4k sectors. I found a way to manipulate fdisk so it would start the partition on the correct cylinder or whatever to take advantage of the new format. I also ended up using GPT instead of MBR because it had more usable space.
two 2TB drives, GPT, ext4, 4k sectors
two 1TB drives, GPT, ext4
one 1TB drive, MBR, NTFS (not important)
This setup was working fine for a few days until I had to take the server down to move some wires around. When I booted the server back up, I discovered the two 2TB drives were missing. They showed up in /dev but wouldn't mount.

I have one machine with two disks that I'd like to install Slackware on. I'd like to have the root folder and installed folders on hdb, and just have have hda as a disk I can use for storage (without any home directories, etc.). My problem is, I don't know how to make this boot, as I think LILO is installed on the primary drive, but the boot folder is located on hdb. I tried doing this before and was having problems booting, so I was just going to go through the whole process again, but don't really know the correct procedures.

After I complete a big project I'm working on I'm going to be wiping and re-doing my desktop machine, probably in the next day or three. I'm going to be setting up a dual-boot; my first in about three years. I'll be using separate hard disks for this, and installing Slackware second on the bigger of the two drives. When I've done this in the past I've used Grub; Is there anything I need to know or pitfalls I need to avoid doing it with Lilo?

I just bought a USB hard disk and when I plug it in it gets mounted as owner root and group root. I tried writing a udev rule for it based on the following guide:Nothing seems to work, it always mounts as root. Slackware 13.1, KDE, Dell Optiplex GX280, Western Digital Passport USB 320 gig drive.I am a member of the plugdev group, so it seems to me a rule should not even be necessary.

I know I can simply create a degraded raid array and copy the data to the other drive like this: mdadm --create /dev/md0 --level=1 --raid-devices=2 missing /dev/sdb1
But I want the specific disk to keep the raw ext3 filesystem so I can still use it from FreeBSD. When using the command above the disk will be a raid disk and I can't do a mount /dev/sdb1 anymore. A little background info. The drives in question are used as backup drives for a couple of Linux and FreeBSD servers. I am using the Ext3 filesystem to make sure I can quickly recover the data since both FreeBSD and Linux can read from that without problems. If someone has a different solution for that (2 drives in raid 1 that are readable by FreeBSD and writeable by Linux),

I just partitioned and installed slack on a 1TB hard drive. I then run KDiskFree under KDE, and saw that I am missing about 300Gig! Is it just a simple thing between bytes and bits like MS. Or is this an issue I can not ignore? I have 3 partitions. One is my swap, one is ext4(slackware is on) the last is a jfs partition.

I am building a home server that will host a multitude of files; from mp3s to ebooks to FEA software and files. I don't know if RAID is the right thing for me. This server will have all the files that I have accumulated over the years and if the drive fails than I will be S.O.L. I have seen discussions where someone has RAID 1 setup but they don't have their drives internally (to the case), they bought 2 separate external hard drives with eSata to minimize an electrical failure to the drives. (I guess this is a good idea)I have also read about having one drive then using a second to rsync data every week. I planned on purchasing 2 enterprise hard drives of 500 MB to 1 GB but I don't have any experience with how I should handle my data

I have Fedora 14 installed on my main internal drive. I have one Fedora 14 and one Fedora 15 installed on two separate USB drives.When I boot into any of these drives, I can't access any of the other hard drives from the other drivesll I can, but just the boot partitions.Is there any way of mounting the other partitions so I can access the information?---------- Post added at 12:42 PM ---------- Previous post was at 09:34 AM ----------I guess even an explanation on why I can't view them would be good too.

I have a SATA drive that worked fine. Then I installed two more hard drives into my system. When these hard drives are installed, if I try to access the SATA drive in Linux, it will start lightly clicking and then the drive will become unavailable. If I power on the machine without the other two hard drives then it works fine. What could be causing this to happen? I don't think it's heat because the two hard drives are far away from the SATA drive.

I am building a minimized 6.2.2 linux kernel using slackware on a dinosaur of a computer: AMD Athlon +1700 Single Core processor, 1gig of DDR SDRAM. This is my first time compiling a linux kernel, so before I make any major mistakes, I could use some help in determining which filesystems I absolutely must enable support for. Ext2 is allready in.

I have a Centos 5.5 system with 2* 250 gig sata physical drives, sda and sdb. Each drive has a linux raid boot partition and a Linux raid LVM partition. Both pairs of partitions are set up with raid 1 mirroring. I want to add more data capacity - and I propose to add a second pair of physical drives - this time 1.5 terabyte drives presumably sdc and sdd. I assume I can just plug in the new hardware - reboot the system and set up the new partitions, raid arrays and LVMs on the live system. My first question:
1) Is there any danger - that adding these drives to arbitrary sata ports on the motherboard will cause the re-enumeration of the "sdx" series in such a way that the system will get confused about where to find the existing raid components and/or the boot or root file-systems? If anyone can point me to a tutorial on how the enumeration of the "sdx" sequence works and how the system finds the raid arrays and root file-system at boot time
2) I intend to use the majority of the new raid array as an LVM "Data Volume" to isolate "data" from "system" files for backup and maintenance purposes. Is there any merit in creating "alternate" boot partitions and "alternate" root file-systems on the new drives so that the system can be backed up there periodically? The intent here is to boot from the newer partition in the event of a corruption or other failure of the current boot or root file-system. If this is a good idea - how would the system know where to find the root file-system if the original one gets corrupted. i.e. At boot time - how does the system know what root file-system to use and where to find it?
3) If I create new LVM /raid partitions on the new drives - should the new LVM be part of the same "volgroup" - or would it be better to make it a separate "volgroup"? What are the issues to consider in making that decision?

My system is setup like this: 1 250 gb HDD, with a 20 gig partition for /, 200 gigs for /home and the rest is a swap file. I also have a 1 TB (ext3) and 1.5TB (ext4) hard drive that are also installed, mounted to /Shared_1TB and /Shared_15TBI just installed Ubuntu 9.10 and everything seemed to be fine. I installed all the updates, install the Nvidia proprietary drivers and got my HDMI audio working. I went to try and play a video to see what would happen.... there are no files in /Shared_1TB. It is totally blank. I tried making myself the owner, and while this worked it didn't help anything. I tried unmounting and remounted, however it kept saying it was busy and wouldn't remount it. At this point I was a little panicked, so I threw in a LiveCD and low and behold once I mount it in the LiveCD all my files are there.

I recently purchased 3 new WD cavier green 500gb drives with the intent of building a raid5 array and running linux. Admittedly I purchased without doing enough research and now I have serious doubts about running an os on raid5 with the onboard controller.So now I am thinking I should run one drive as an OS drive and mirror the other two. I don't have a fourth drive unless someone can convince my wife I need a fourth after already buying 3....
Is it possible to have multiple distributions where ALL distros save their docs to the raid dives? That way I can wipe/install the os and keep my files? I seem to recall that I can be done, just need someone to point the compass.

i have 2 hard drives showing up on my desk top and when i try to unmount them i get an error
Error unmounting: umount exited with exit code 1: helper failed with: umount: only root can unmount /dev/sdc1 from /media/new movie storage
and
Error unmounting: umount exited with exit code 1: helper failed with: umount: only root can unmount /dev/sdb1 from /media/STUFF
when i try to unmount the other one. now one problem i see is that the labels are wrong the error for /media/stuff came up when i tried to unmount /media/new movie storage, and and the other way around for /media/stuff. also new movie storage is labeled as safe every ware else including inside windows

Earlier I had two physical hard drives in my computer, one with Windows and one with Ubuntu. Now I have a new computer and have installed these hard drives in it. I run Windows 7, and I can find the Windows disk, but not the Ubuntu disk. This doesn't surprise me, as Ubuntu is another filesystem, however, earlier I could format it with a partition manager, but now I didn't even find it with that!

I'm looking for a way to set up a backup with two 2TB hard drives. What I want to do is basically mirror two drives. What ever I copy to the one drive I want it to be "cloned" with the other drive.
Is there any software that could help me with this? Does anyone know of a better to do something like this?

I have a nice computer i have been dual booting between either ubuntu or win7. i am wanting to remove win7 and install winxp sp3, so i can use media center with my xbox. i preferred that win7 work, but since my copy is not genuine, its authenticity is believed to be the culprit in connection errors with the xbox. i have not been able to find a linux alternative, which i doubt even exists due to the proprietary nature of the xbox.
So, my question is how do i reformat the win7 hard drive? are there issues i need to worry about that may reformat both hard drives on accident? and when the hard drive is formatted, will i be prompted to choose which hard drive to install win xp on?

My computer has 2 40GB hard drives (yes, it's really old). One of these hard drives has Ubuntu installed on it, and I would like to use the second hard drive as a data storage device that is usable by anyone who just wants a random place to drop random stuff. How do I do this?

I am trying to install windows 7 over Ubuntu, however when i run the install disk it tells me that my hard drive is not formatted in the correct format. I have then loaded up Ubuntu, tried to re-format using Gparted and it won't let me re-format my hard drive when I right click on it. The only option I get when right-clicking is to unmount the drive.

I have ubuntu 11.04 installed on a 80gb hard drive and everything was running fine. I then installed a second drive (1gb) for storage. It worked fine after a reboot but now it won't boot. I'm pretty sure it's just confused as to which drive is the boot drive. I'm not sure as to how to fix it in GRUB2.

I have approx. 30x Western Digital SATA 2.5" hard drives ranging from 80GB to 500GB. These are ex-Tandberg RDX QuikStor backup drives that I no longer use and would like to use them as spare laptop hard drives.The only problem is upon installing the drive in a laptop it prompts for a hard drive user password.
Are there any open source methods to wipe the password (and data; I don't care about that)? I've tried using various wiping methods (dd, dban etc.) but the password still remains.Any help is greatly appreciated; I really need these drives.Plugging it in via a USB HDD enclosure shows as /dev/sdb but does not respond to (c)fdisk or show any partitions (/dev/sdb1 etc).

When the computer starts, you will read a flashing message about S.M.A.R.T and a few other things.I have two hard drives. There is a strange noise from the computer when I run it for more than 3 or 4 hours continuously. I firmly believe one of the hard drives is not working properly. I saw a message about a problem in S.M.A.R.T.It was a flashing message. I couldn't read it. I don't run any Windows on the computer. All are Linux. The default is Mandriva.
How do I read the flashing message you see at the start of a computer? I want to find out the damage one replace it with a new one.

I know this is an easy task, especially using cPanel. However I want to do this without formatting the drive, since there is sensitive data already on the hard drives. So how would I mount a hard drive, but not format/lose any of the data already on it?I've looked and everything seems to lead me to believe that I'll lose data if I do it that way.
