Feb 18, 2010When 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.
General :: Filesystems - File System For Removable Storage?
Apr 7, 2011I have a 500GB external drive I want to use on a couple of Linux systems, and looking for a filesystem for it. External drives are frequently formatted in FAT32, but I don't need to interoperate with Windows and would rather avoid the ugly limited kludge that is FAT.
Since I only need to use it on Linux, I would use ext4 or XFS, but they store ownership information. Ideally, I'd use a proper Unix file system that doesn't track ownership (files are owned by whoever mounts the device, like they are when mounting a FAT32 partition), but I do not know of any file system that does that.What would be a good file system for this disk?
General :: Root File System Partitioning - Filesystems ?
Feb 12, 2010I've been using *Unix systems for many years now, and I've always been led to believe that its best to partition certain dirs into separate FileSystems, off the main root FS.
For instance, /tmp /var /usr etc
Leaving as little as possible on the main / system.
Its so that you don't fill up the root system be accident, by some user putting in too bigger files in /tmp, for example.
I would presume that filling the / system would not be too good for Linux, as it would not be able to write logs and possibly other things that it needs to.
I believe that if root gets full, then there is something like a 5% amount saved for just 'root' to write to, so that it can do its stuff.
However, eventually, / will become full, and writes will fail.
On top of this, certain scripting tools, such as awk, use the /tmp/ system to store temp files in, and awk wont be able to write to /tmp/ as its full, so awk will fail.
However, I'm being advised that there is no need to put /tmp /var etc onto separate FSs, as there is no problem nowerdays with / filling up. So, /tmp /var /usr are all on the root FS.
I'm talking about large systems, with TBs of data (which is on a separate FS), and with a user populations of around 800-1000 users, and 24/7 system access.
Ubuntu :: Changing File System Type To Another Filesystem Type - Does It Effect On Data?
Feb 4, 2011In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I had very imp data in d:drive
General :: Accidentally Type Concatenate Large File On Remote System
May 6, 2010Every once in a while on a computer I'm ssh'd into, I will accidentally type "cat largefile.txt" and my screen will start rushing with text for the next 10 minutes. I'm always working in a screen session, so my current solution is to just log out and then log back in, and since it can go 100X faster when I'm logged out, it'll finish in the short time it takes me to type my password in again. Is there a better way? Either involving the fact I'm in a screen session? Or a way to do this within SSH? What doesn't work: detaching from the screen session (doesn't respond until file is done outputting) trying command to move to a different window in the screen session (also doesn't respond) typing ctrl+C to kill cat command (also doesn't respond, probably because the command is done and the buffers just have to catch up).

General :: GRUB Legacy - Unable To Determine The File System Type?
Dec 8, 2010I had only Arch on an HDD.sda2 was "/".Now it's with Windows XP and sda2 is not a root any more but a container partition wich has sda{5,6,7} in it. I configured the dual boot and it works. It finds Arch and boots it, but not completely. Stops after some time and says: unable to determine the file system type of /dev/sda2. FSTAB is configured, sda{5,6,7} are on their places. So I can't boot Arch. XP boots correctly. What do I do with this error?Also it says: try adding rootfstype=your_filesystem_type to kernel command line.

General :: Removing Previously Type Commands At A Remote Server?
Aug 7, 2010I am ssh'ing into a remote server and then su'ing to root.The problem is that sometimes, I have not paid enough attention to the console message, and I have accidentally typed in the root password at the command prompt (when for example, I had failed to provide the root password correctly the first time - so su prompt went away).
I remember reading somewhere that a history of commands typed at the console is kept somewhere.I have 3 sub questions
Where (which folder) is the file stored?
Can I edit that file and remove the root password from it?
Being the paranoid person that I am, I wonder if there is a more secure way of logging into my server - other than ssh (or am I being TOO paranoid?)

General :: Debian System Drive Upgrade: Copy Filesystems From MBR Partitions To GPT?
Jan 23, 2010My home server runs Debian Lenny, and I'm about to upgrade the system drive to a larger drive.In the process, I want to take the opportunity to reorganize the partitions and resize them. For learning purposes, I'm planning to migrate from an MBR partition table to GPT.Because of those two changes, I can't just run "dd if=/old/drive of=/new/drive" (well, not without lots more work afterwards). I could use the debootstrap process to get a fresh installation on the new system drive, but I used that technique during the last system upgrade and it's probably overkill for this.Can I just copy the partitions from the old drive to the new?Will "dd if=/dev/hda1 of=/dev/hdb2" work, assuming /dev/hdb2 is larger than /dev/hda1? (If so, the filesystem can be resized to take advantage of the new larger partition, right?)Would parted (or gparted) be a better tool for copying the contents of the partitions?
View 3 Replies View RelatedGeneral :: Filesystems - Convert A Disk Image Into A Sparse File?
Jul 31, 2010I have a bunch of disk images, made with ddrescue, on an EXT partition, and I want to reduce their size without losing data, while still being mountable. How can I fill the empty space in the image's filesystem with zeros, and then convert the file into a sparse file so this empty space is not actually stored on disk?
For example:
> du -s --si --apparent-size Jimage.image
120G Jimage.image
> du -s --si Jimage.image
121G Jimage.image
This actually only has 50G of real data on it, though, so the second measurement should be much smaller.
This supposedly will fill empty space with zeros: cat /dev/zero > zero.file rm zero.file But if sparse files are handled transparently, it might actually create a sparse file without writing anything to the virtual disk, ironically preventing me from turning the virtual disk image into a sparse file itself. :) Does it? Note: For some reason, sudo dd if=/dev/zero of=./zero.file works when cat does not on a mounted disk image.
General :: Filesystems - Best File-systems / Mount-configuration For Each Folder On GNU?
Apr 10, 2011One of the good points of linux is that is easy to customize the partitioning scheme of the disk and put each directory (/home, /var, etc) in diferent partitions and/or diferent disk. Then we can use diferen file system/configurations for each of them for make them better. xamples:
noatime is a mount option to not write access time on the files. data=writeback is an option to layz write metadata on new files. ext3/4 has journaling that make the partition more secure in case of a crash. bigger blocks make the partition waste more space, but make it faster to read and may become more fragmented. (not sure) Then: What are the best filesystem/configurations for each directory? Note: given the answer of Patches, will only discuss /, /home and /var only.
/var -> It's modified constantly, it write logs, cache, temporal, etc.
/home -> stores important files.
/-> stores everything else (/etc and /usr should be here)

Dec 29, 2010We have recently built some RAC (OS:RHEL55) servers and after the Oracle guys have installed their application, somehow the directory / is using the maximum space. I contacted the Oracle team & they say that their RAC installation doesn't create any files in the / directory. This is the o/p of '/' directory file system:
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/datavg-vol2 498M 382M 62M 88% /
Also, when I checked the file sizes, I found that the following files were taking more space:
/etc/selinux/targeted/modules/active/
-rw------ 1 root root 17M Nov1 base.linked
[code].....
I don't know what these files are doing there, when I did a cat and cheked, I found the files containing this data:
nf_tre--
stem_dbusd_var_run_t...and some stuff like this Unable to decide whether or not to remove these files. Also, is there any way to find out what files are taking more space and whether they can be deleted or not? in order to free up some space in the / direcoty. As there are 10 RACs that we've build, I got to do something to fix this for all of the 10 servers.
General :: How To Find The /dev/Device Mapping For NFS File System In RHEL
Jun 19, 2010Found the below from RedHat Knowledgebase
The Completely Fair Queuing (cfq) scheduler in Red Hat Enterprise Linux 5appears to have worse I/O read performance than in version 4. It appears as though the Completely Fair Queuing I/O scheduler (cfq) has a regression and thus exhibits reduced read-side throughput which can affect performance for both local and NFS mounted file systems.
One way to mitigate this is to set the cfq's slice_idle parameter to zero. To change this value, execute the following command echo 0 > slice_idle in the /sys/block directory appropriate for your situation, as shown below:
echo 0 > /sys/block/hda/queue/iosched/slice_idle
We are using NFS file systems in RHEL 5.3. I would like to know how to find which /dev/Device is being used by the NFS file systems, so that I could try setting the slice_idle to '0' to see if there is any difference in performance? In /etc/fstab I only see the actual NAS volumes for the NFS file systems.
