Assume I have plugged in an external USB hard disc.
How can I find out (from terminal cmdline) the file system (ext2, ext3, reiserfs,...) of this hard disc?
From Ubuntu I know the two commands:
sudo blkid -c /dev/null
or
sudo fdisk -l
but these are not known in CentOS.
What are the corresponding cmds in CentOS?
I have just installed 11.3 x64. The installation went fine and worked for the first few hours. I ran the online update tool, and now it cannot find grub unless the installation disc is inserted and I select the "boot from hard disc" option.
I have read about the problem of the root partition being back, but not sure that's it.
sda1 - swap
sda2 - /
sda3 - /home
There used to be a repair tool in the installation disks. I could not find that in this media. Is that still available?
I have a 1.5TB Western Digital Caviar Green in a USB 2.0 external setup with an ext4 file system. I'm going to purchase a 2.0TB Western Digital Caviar Green in a USB 2.0 external case, copy the data over and put my 1.5TB in a fire-resistant box in another house. I'm worried about a couple things however:
(1) I'm worried about the long-term viability of _any_ file system years into the future. I've been storing my data on hard drives (instead of CDs, DVDs or BDs) for years now due to their higher reliability than optical disks. However, the file system used in optical disks is UDF which I think has much longer viability into the future. I'm not going to store terabytes of data on optical discs of course, so I'm wondering what I should choose for a hard drive file system. FAT32 or NTFS (due to Windows' 90%+ presence on the desktop, including still being used by Windows 7) may be the best choice, but I much rather have a open source file system, especially one that allows for permissions, timestamps, etc.
(2) As for my 2TB hard drive that I will be using for a while into the future, should I continue to use ext4 (I've had no problem with it thus far), but is there another file system that has better performance when storing and transferring gigs of data?
I have a few computers all connected to the same router both wireless and wired. All at the moment are running Ubuntu. There is no problem sharing any of these computer's local drives through the network. However I have one desktop with an external USB Hard disc plugged into it. I would like to share this external hard disc on the network. I set it up to share but when I try and access it from one of the other computers on the network, although it shows up, I get the message "Unable to mount location. Failed to mount windows share".

View 3 Replies View Relatedi needed to change my external hard drive's file system from ext3 to fat32, to use it in windows, which i did the simple way: i shrunk the ext3 partition, made a fat32 partition, copied the files over, removed the ext3 and made the fat32 bigger. unfortunately, while gparted was making the partition larger, my computer shut down. i lost all my files and the partition messed up immediately. i made a new fat32 partition, after deleting the old one, but noticed that gparted was showing 100 gigs already in use (???). so now i have a 300 gb hard drive with only 200 gb i can use; i ran df to make sure gparted wasn't messing up, but indeed it shows the partition as being only 200 gigs in size. i haven't tried making any other kind of partition yet, such as ext3, for fear of losing my files again, and because it wouldn't be permanent anyway, because i need those files in windows and stupid microsoft won't make their OS ext3 compatible.

View 1 Replies View RelatedIt started when I wanted to dual boot Windows 7 and Opensuse off of my netbook (No DVD/CD drive) I tried install suse from an external hard drive and I botched it. I ended up erasing EVERYTHING off of my internal netbook hard drive. Windows and all.
Well, I had a couple of other computers so I studied up and eventually successfully installed OpenSUSE 11.2 on my external hard drive (11.3 being the one that I accidentally erased everything with, so kinda scared of it) and now I want to install openSUSE 11.2 on my internal netbook hard drive.
I can not use disks
I can not use a flash drive (For some reason, even if I make it bootable, it will not load up, this could be because it's actually a 8GB microSD card that is placed in a USB card reader.)
I can not use an external hard drive because that's what I'm running suse off of.
I've tried reading up on how to install suse on another drive off of the hard drive and I've gotten as far as whenever I boot up the netbook with the suse external hard drive connected it will ask to boot into OpenSUSE, the Fail Safe, or to install OpenSuse. When I select to install it it gives me the Error 18 Unknown File system.
I've tried formatting the internal hard drive twice. One as NTFS and again as EXT4. Neither seems to effect it other than when it's ext4 I can open it and it contains a Lost and Found folder.
When I interrupt the boot sequence by pressing c and going to the terminal and I use the root (hd +TAB command it tells me I have a hd0 and a hd1. The hd1 only has 1 partition which is ext4, which I'm assuming hd1 is the internal hard drive (I'm not sure how to check) and the hd0 is the external hard drive, which has three partitions. One with an unknown file system and two with ext4. When I try to enter the set up from the terminal it gives me the same error for any thing I put it (e.g. root (hd0,0) gives the same error as root (hd0,1), or root (hd0,2) and root (hd1,0)
Something like it cannot locate these two files I'm assuming it needs to boot. If anyone finds this relevant I'll retry it and post the files its missing.
I've been searching for awhile and can't find any threads that can solve my problem. From other threads, however, I have noticed that I should probably include my menu.lst, listed below

I have also ran the boot info script and received the RESULTS.txt file it generates. Listed below

I'm trying to get my work's infrastructure built at home before I go up there and show the boss. It is as follows: VMware esxi installed on the server with:
Windows server 2008
Ubuntu 10.04 server
I've got VMware installed. And I have spent the past 7 hours trying to figure out how to manage it. I found out that vsphere has not nor will ever be supported for Linux; which was my first problem.
Second Problem So I had to dig around for a spare Windows 7 dvd. To my UN-surprise it blue screened before it even got to the Windows installer.
Third Problem So I dug around for my Windows XP disc. Wouldn't find my sata hard drive and I wasn't about to dig around for a floppy drive and disk, in order to install it.
Fourth Problem I remembered that I had a dual boot of Windows 7 downstairs and proceeded to download and install vsphere. It wouldn't install because of some updates that needed to be installed. I installed them and got vsphere installed as well. However upon connecting to my vmware esxi, there was yet another error that had to do with some update. I found out that the error had been existent since 2009 and for some reason NO ONE at VMware has fixed it....
Having problems with external hard drives. I may be wrong, but I suspect they originated with an upgrade to 10.04 last Christmas. Around that time I also started using Amazon's S3 storage system, and, as a consequence, I stopped using my WD 80G external drive, previously used to backup my important files.
A week or so ago I decided to start using the WD drive again. I can't remember exactly what I did, but it wasn't happy - never caused any problems before. When I plug it in, the on-off light as the front keeps flashing on and off, and when I try to remove the drive I get the message: Error unmounting volumne An error occured while performing an operation on "My Book" (Partition 1 of WD 800BB External): The device is busy
Details: Cannot unmount because file system on device is busy Assuming the device had died - it's about 5 years old - I bought a 160G Samsung S-Series drive - my but they do look neat! Unfortunately, this doesn't seem to have solved my problem. I plugged the new drive in, and it happily appeared on my desktop. It seemed a good idea at the time, but I then started to format the drive - using the default option of FAT. All went well at first, but then the format process stopped.
My new Samsung drive now seems to be operating pretty much as the WD device, I can't copy to the drive, and attempts to unmount it generate a response similar to what's happening with the WD drive. Currently, although plugged in, I can't see the drive on my desktop, although it appears under Places. However, when I try to mount the drive, I get the message: Unable to mount SAMSUNG A job is pending on /dev/sdb1
When I run 'parted' and then type 'print' to see the partitions that are available, I see two entries: /dev/sda1 and /dev/sda2. /dev/sda1 is of ext3 type whereas for /dev/sda2 nothing is specified for file system type. The LVM flags are set for /dev/sda2.
When I tried to resize /dev/sda2, it gives me the error "File system type not recognized". let me know how to find out the file system type of the partition.

View 2 Replies View RelatedIs there any software that will do full mirroring between a local and a remote file system. I have a server (9.04) and a laptop (9.10). Each user has shared a shared directory on the server, and on the laptop. Updates to files may be done on either system. I want to keep both copies syncronised. Currently I use a script based on rsync (scheduled by cron) to keep the local and remote copies in sync.
The problem with this approach is that rsync only seems to be able to handle deletion of files if one file system is the master, which is not the case in my set-up. If I move a file to a different directory, rsync will reinstate the old file as well as copying the new one. I was hoping there was some software that could do proper mirroring between the 2 systems, but6 so far I cannot find anything.

This is Mushtaq here. I am using CentOS 5.3. Everything works fine regarding Hardware Support except of External Hard Disk. I have a HDD Western Digital 80 GB in USB converted case. Its working fine under WinOS, Fedora 10 / 11 / 12 + & RedHat Enterprise Linux. But CentOS is unable to access it even it does not detect it (fdisk -l command is used to verify the connected disks). Can any one please help me in this regard, I am fed-up of this situation.

My father installed Kubuntu to his external hard drive to try it out, however, it is running extremely slowly. It takes a good minute and a half to boot to the Plasma desktop and it even seems to run faster off of the LiveCD.His system easily meets the specifications to run Kubuntu (4 gigs of RAM, decent NVIDIA graphics card) yet it slows to a crawl immediately upon booting. Does anyone know how to fix this? The hard drive is a Western Digital MyBook, 475GB model.
View 4 Replies View RelatedI've installed Ubuntu 11.04 Natty Narwhal on a External HDD (320GB Samsung S2). Worked like a charm. Bit slow to boot up and load programs, but after a while, works great. I installed it on the external HDD for one purpose: Work anywhere with Ubuntu, no matter which computer I use. I was thinking that was impossible, but I've tested thru several platforms (3 Notebooks, 2 netbooks, all Intel and one AMD Desktop). All worked flawlessly (32 Bits PAE activated and no matter how many cores are active, just works), BUT the themes.For no apparent reason, themes works on the computer I've installed Ubuntu on the HDD. It has his own Internal HDD with Windows 7 and two NTFS partitions.
Themes are stuck to the default boring-white from Gnome. I can only change the window controls. Compiz works, Wireless works, video works, sound works, filesystem works, system works - themes fail. Feels like I've hit my feet's little finger on a chair. P.S.: Ext. HDD is partitioned like this: 300GB FAT32 (it's my pop's HDD, he wants it this way), 18GB EXT4, 2GB Swap.

Find external and internal devices attached to a system in Linux
How can i find through terminal that which devices are external and which are internal.
By external i mean devices attached to USB port. For Example, USB Drive, Portable USB HardDrive etc
By internal i mean devices attached internally. For Example, SATA Harddisk etc.
i want to move a directory to an external hard drive this is what i did
Code: konlah@konlah-laptop:~/Downloads$ sudo mv -i LinuxCBT /mnt/EXTERNAL after that i did
Code: konlah@konlah-laptop:~/Downloads$ ls so the file wasn't there anymore.. but i couldn't find it in my external hard drive.
I plan to reformat & reinstall my linux (centos).Before doing this, I got to backup my files into my USB external hard disk from Seagate (FreeAgent). The problem I faced is that I could not copy file into the hard disk even I was in root user. It prompted me that it is only read-only. I just wonder why.I have tested with my thumb drive. It worked. May I know why I could not copy file to the USB FreeAgent hard disk. Due to file system?
