Ubuntu Servers :: Samba Filesystem Type Impacts Performance?
Jun 4, 2010
I installed a month or so ago a Samba File Server along with Active Directory integration in my company. I choose to install on my newly created raid array, all in ext3 filesystem. The purpose of this fileserver is to have lots of files from the different departments on the company (all windows workstations except mine). Everyone has a private folder and a department folder, along with the common folder for all employees.did I made a mistake formating all to ext3? would I get a significant increase in performance if I resize the current ubuntu partiton and created a new NTFS new one and move the files to it?

I built my own file server based on the Intel Atom 525 and Ubuntu 11.04 (amd64):http:[url]....It has 2 2TB Western Digital Green drives connected via SATA.Internal file transfers (disk-to-disk) using Nautilus zip along at 80 Mb/sec. Over SAMBA, however, I'm getting 35 Mb/sec. Other than creating the shares, I haven't modified smb.conf.have a gigabit network. I've run atop on the receiving computer and it isn't being taxed. At 35 Mb/sec the file server is also not being taxed.
Should I be focusing on testing the onboard NIC (RealTek 8111E) in the file server or looking at SAMBA?

In 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

I have a following problem: Recently my drive with Ubuntu 9.4 has mysteriously stopped working, i.e. when I switch the computer on it informs me that GRUB didn't find the filesystem. Well, I suppose it happens.
First, I though it was due to the drive dying, but I popped it in an external enclosure and HDTune told me the drive was fine. Wanting to recover the files on the drive before reinstalling I first tried to mount it in said external enclosure under Windows (I have Win Ext2 driver installed which used to work just fine). This time, however, drive gets assigned a letter but upon opening it Windows popped up an error saying that the drive was not formatted and whether I would like to format it then.
Unfazed by this streak of failures I tried to mount it under Linux but, alas, to no avail. I might have tried every single -t operator under mount command but it still won't budge and let me mount.

When I try to boot to OpenSUSE I get the following error during boot-up: unknown filesystem type 'reiserfs' could not mount root filesystem - exiting to /bin/sh$
This only started happening quite recently - before this I could boot to Linux quite happily.

I am trying to mount a file image, like this
mount -o loop /tmp/apps.img /media/apps
But I get the following:
mount: you must specify the filesystem type
I try ext3:
mount -o loop /tmp/apps.img /media/apps -t ext3
dmesg says:
error: can't find ext3 filesystem on dev loop6.
I've also tried ext2, vfat etc. How can I detect the filesystem type of apps.img?

Code:
fsck from util-linux-ng 2.17.2
e2fsck 1.41.11 (14-Mar-2010)
/dev/sda1 is mounted.
WARNING!!! The filesystem is mounted. If you continue you ***WILL***
cause ***SEVERE*** filesystem damage.
Do you really want to continue (y/n)?
I don't want to cause damage, but I'd rather not go into BIOS.

I changed the first line of /etc/fstab in an attempt to get rid of an annoying message "mount: unknown filesystem type 'static'". All I did was put a "#" on the first line .... changing the original from:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
to:
#
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
I have tried desperately to get to the file system so that I can edit that first line in fstab out but nothing works and the file system comes up as read only ...

As per these instructions, I got up to the end of the "Acquiring an Ubuntu filesystem" step (where it asks you to mount the newly created Ubuntu partition) and ran into a problem: The partition won't mount, as the file system type cannot be determined because I cannot remember the file system used during installation. Is there any command that prints the file system type of GPT partitions?

Using tar is it possible to backup different types of file system e.g.ext3, ufs, or any other file system. I know using dump it is not possible because it is reading through raw device. Then what about tar? Where I get more info about this? Means suppose I want to backup files from different file systems using tar then is it possible?

I have a WinXP virtual box and have setup a Samba server to have it use directly a couple of directories on the Linux side. The Samba performance is definitely better than the built-in shared folders of the virtualbox, but there is nothing to write home about either: transfer seem to top at around 3Mbyte/sec.
The machine is a laptop (Core i5 CPU (M520@2.40GHz) and a 7200RPM HDD) running Kubuntu 10.04.The Samba share uses a dedicated "host-only" network adapter. There is an iptable-based firewall to which i added the required 4 statements to let the Netbios traffic go through (without them nothing works...)So, given the hardware, are the 3MB/s a decent figure? And if not, what should I aceeive, and where can I look improve on the current numbers?

I just got an Acer netbook Aspire One. I put the Ubuntu remix on it successfully, and was using it for several days without problems. Now all of a sudden when I turn on my computer I get a grub error message with a command prompt. I've tried following the direction to restore grub but I'm getting stuck right away on the command to mount my ubuntu partition. After I type "sudo mount /dev/sda4 /mnt", I keep getting the error message "mount: you must specify the filesystem type."

I recently upgrade my armel NAS from etch to squeeze. During the partitioning step of the installation I intentionally left unmounted the data partition (900GB formatted XFS) but after the installation I'm not able to mount it.
I edited the fstab file adding the last line
And tried a mount but I get the message
So i noticed throught lsmod that I don't have the module for xfs
Tried installing xfsprogs but it didn't helped. So I searched for xfs-modules but seems it doesn't exists for armel architecture. Am I right? What does it means? That XFS is not supported in armel Squeeze? Assumed I can't transfer/backup 900GB of partition, is there a way to convert it on-the-fly to a supported filesystem format?

I had installed ubuntu 11.04 on my system along with windows vista. After a few days, i decided to remove ubuntu so i just logged into windows and formatted the ubuntu partition using the windows partitioner, then extended my main c: drive to span the whole disk so that i was left with a single partition with only windows vista on it.Later when trying to restart my system couldn't log back into windows.I kept getting a prompt sayinggrub rescue>After googling around a bit i shrinked and created another partition the disk again and installed ubuntu on it again.still. =/GRUB doesn't show any windows entry.I noticed something strange though that when i tried viewing my partitions using parted i didnt see any filesystem type listed besides my windows partition (/dev/sda3). I doubt that is why GRUB does not show any windows entry.Also i manually tried to boot into windows from the grub prompt using commands...root(hd0,3)chainloader +1bootbut it says 'invalid signature'Did i somehow corrupted my windows partition during resizing and installing/un-installing? Plus i also booted with the windows installation dvd and when i typed bootmgr /fixbootit said something like no valid filesystem found.

I dont know anything about linux and just been assigned to amount a drive to it. here's what i did so far: Version of Linux using Red Hat Enterprise Linux Server release 5.3 (Tikanga) [root]# mount -t auto /dev/sdb1 /tmp/archive mount: unknown filesystem type 'ntfs'
when checking the /proc/filesystems, i noticed that 'ntfs' is not listed there, several forum suggested i try running 'modprobe ntfs'. If that is not found, you'll need a kernel with ntfs support. i'm so lost, where to i get the modprobe ntfs

I have installed a linux server, centos gui server with Raid1, his role will be only a file server. I installed samba and configured it. The file system is EXT3. the server got 4 gigs of memory.There is a program in windows that writes files to the share.I searched and i found that there is some commands that you add and they boost the performance.
I got complains that the writes are not fast enough. Before me another IT guy configured the file server and it was faster, what he told my customer that he changed some command of cache but i dont know exactly what he did. I have been asked to find how to boost the performance.Please give me more commands to try to boost the performance of Samba or tell me if i need to change anything..

I'm trying to mount an external DVD +RW Drive so I can burn a directory from my Linux Server to disk. I think I've figured out how to mount the drive, but it only works when there's a disk with data in the drive. When I enter mount /dev/scd1 /mnt I'm able to read from the drive, no problem. When I try to do the same thing, however, with a blank disk I get the following message: "mount: you must specify a filesystem type" So I'm assuming I need to prepare the disk somehow. I've verified that the dvd+rw-tools package is installed on the RH server but I'm not sure what the next step is.

Formated new drive with ext3 on external drive on Suse 11.1 When upgraded to 11.2, drive was not connected... Could not get mounted after that... Set up another boot drive, could not get to mount. Found post with following:
>cryptsetup luksOpen /dev/sde1 restore
>mkdir /restore
>mount /dev/sde1 /restore
Error as follows: mount: unknown filesystem type 'crypto_LUKS' Have also got to another point where superblock was incorrect. I can use terminal, but am not a linux guru... Have looked at other posts under luks, but can not find a solution.

I wish to prevent the samba messages (mainly nmbd and winbindd) from appearing in the system log (/var/log/messages). I want to allow samba logging to the standard samba logfiles, but prevent the syslog getting clogged up by samba. I added syslog = 0 to smb.conf and reloaded the config but the messages were still appearing. I also tried the following (and restarted the syslog via /sbin/service syslog restart) # Suppress messages from samba.
nmbd.* /dev/null
smbd.* /dev/null
winbindd.* /dev/null
For interests sake the messages I'm getting are below (I'm not concerned about the messages themselves, I can chase them up at my leisure via the samba logs) Mar 18 09:58:29 SERVER nmbd[3808]: query_name_response: Multiple (2) responses received for a query on subnet xx.yy.z.zz for name DOMAIN<1d>. Mar 18 09:58:29 SERVER nmbd[3808]: This response was from IP xx.yy.z.zz, reporting an IP address of xx.yy.z.zz.
