As from Hardy 8.04, Ubuntu started to use relatime as default. I just noticed today that the entries in Lucid's default /etc/fstab do not have relatime. Surely this is an important omission? On slow computers, it will decrease performance, and on any computer, it decreases the life of the hard drive. That's what I had understood. Or is there something about ext4 that makes this different?
View 3 RepliesI'm probably missing something noobishly obvious here. I recently did a fresh Lucid install on my main desktop box, which had previously been running Karmic. With Lucid I can no longer use fstab in my laptops to automatically mount the desktop's shared media drive. Using the mount command works fine. One laptop is running Karmic, the other is running Hardy.This is the line in fstab on both laptops:
Code:
//192.168.0.123/multimedia /media/multimedia cifs username=x,password=y 0 0
This is unchanged since the desktop was running Karmic, where auto-mounting from the lappys worked just

I was trying to know if relatime or noatime was set on a filesystem, but i didn't found the information, neither in /etc/fstab, neither in kernel boot options.
First of all, it seems clear that i don't have the "normal" behaviour on atime:
root@antec:/tmp# rm -f test.txt; echo a>test.txt
root@antec:/tmp# stat test.txt | grep -i 2011
Access: 2011-08-01 21:54:30.000000000 +0200
Modify: 2011-08-01 21:54:30.000000000 +0200
[Code]....
- Is noatime or relatime a default mount options, and if yes, from which kernel release ?
- Is there a way to see the default mount options (ie: how can i see why i don't have the "normal" atime behaviour ?)
What would be the best way list disk and partitions in the fstab file?
View 1 Replies View RelatedI've had two hd's in my box forever. for more space and backup reasons. Well I have started running the Debian Squeeze distro since December. I've had many issues, some are still unresolved. but now I'm running into major headaches with the fstab. Specifically dealing with/wondering why UUID's are used instead of the old /dev/hd? I was a little annoyed when I tried Kubuntu to find /dev/sd? used instead of /dev/hd? but that was workable. But the UUID's are a nightmare. Here's my problem.
My main box is finally giving up the ghost. The mobo is dying. So in order to do some tests I took my hd bundle (my two hard drives with their cables) physically out of the box and temp installed them in a test box. I wanted to do some benchmark and other tests. I got all kinds of errors. I found that the system wasn't recognizing the UUID's listed in fstab. My concern is when the new mobo gets here next week I won't simply be able to plug the hd's in like I always have been and just let Linux reconfigure itself (Debian used to be good about this). I really don't want to have to clean reinstall if it's not needed.
So for this I have two questions. WHY developers decided to drop using /dev/hd? or even /dev/sd? ?
And is it possible to revert fstab's listings back to the old /dev/hd? settings. In debian fstab had lines commented out showing how each partition was listed in it's /dev/hd? status during install.
I'm getting really sick of all these archane changes in ALL aspects of linux that don't seem to have any good explaination or need.
I've apparently changed my fstab file and now my boot drive fails to mount. The original file is still there "fstab.BAK". How do I rename the current fstab to another name and rename the fstab.BAK to fstab? Since this is read only in the /etc directory I have not been able to make this happen from a command prompt.

View 2 Replies View RelatedI have an external hdd that I have added to the fstab so it will mount when I boot. But every time I add the line to fstab and reboot, it hangs during the boot process and says something about ureadahead-other status 4. here is my line in fstab..
/dev/sdc1 /NAS ext3 defaults 0 0
Is there anything wrong with that? I couldn't remember what fs I chose when I formatted it so I did "sudo parted /dev/sdc print" and it said it was ext3.
I upgraded to 10.04 and everything went fine. I had a cd drive fail(wtf?) and took it out, now apparently everything is messed up as far as what is what (sda/b/c/d etc). I've got 2 hard drives, the OS drive was sdb2, with sdb3 /home and sdb1 an ntfs parition. sda1 is /media/disk. sdc0 was the cd drive.
On the next boot up, it was unhappy that something was wrong with the /home partition.(wtf is that, there is no /home "partition", it's /dev/sdb3!), so I was like.. ok just need to go into fstab and re-arrange things. I open up fstab and, most everything is commented out... so I guess 10.04 no longer uses fstab? What does it use now?
Here's my fstab:
Code:
I commented the last two so that the system would boot. Now it wants home on sda3 and media/disk on sdb1, which is fine, but when I change those in the commented section, obviously nothing happens. I would go through and make the file legible, if I knew that Ubuntu still even uses it.

View 3 Replies View RelatedI want to use Access Control Lists (ACLs) on a removable usb hard drive. I don't know how to set up /etc/fstab for usb drives. Every time I try to make an fstab entry for the usb drive I get an error, when I plug in the usb drive and the system tries to automatically mount it. The drive isn't mounted. If I delete the fstab entry for the usb drive, the drive automatically mounts with no problem. However, ACLs are not enabled, because no fstab entry exists to enable ACLs.
The error message states that "only root can mount the drive". However, as far as I can tell, automatic usb mounting is being done by root. When I plug in the drive (with no fstab entry) and it automatically mounts, Nautilus Properties shows the drive is owned by root and has permissions of rwxr-xrwx.
I've got a partition, let's say sdb6, which is one of the partitions of my second hard disk.On boot ubuntu only mount my boot partition, let's say sda2, which is on my first drive.Once ubuntu started if I want to mount a partition I usually click on it under the Places menu and an authorization is required.As I would like to add acl to a partition following this thread

I've tried to add acl option to my fstab, but my /etc/fstab doesn't have any info of any of my partitions and it originaly looks like:
Quote:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name[code]...
My goal is to mount/unmount any partition with acl loaded and graphically ,but I reached my limit on my linux knoweledge.
I run ubuntu 9.10, and my wife runs winxp. I am trying to setup an automount of her storage (D) drive in my fstab. here is the line in fstab:
The share mounts with no errors, but when i go into palces and view the share, it is blank, totally empty. I can create and delete documents here, but the next time I open the share, i cant see anything. If i connect to the share using places>connect to server, everything is fine. If i connect using places, network, and browse to her machine, it works just fine.
Today i did a fresh install of karmic, installed smbfs, added the above line to fstab, same issue. I have searced and searched but I haven't found a problem exactly like this. This setup has been working fine until sometime recently. I cant be sure exactly when it stopped working, or why. The reason I need it to automount is I have several applications that point to that drive. It is worth noting i have tried several variations on the line in fstab, all with the same results.
I'm puzzled as to why this fstab isn't working:
Code:
# /etc/fstab: static file system information.

I'm really tired of having to umount under root, then mount again as a user for my external hard disk. When I'm in firefox, I like to save pages alot onto my external but I constantly have to remount because my user has no write permissions for the drive. What can I do for my device in fstab so that it mounts automatically under my user and not root?
View 9 Replies View RelatedMy HD contains a Windows, Fat32, two Linux & swap partitions. Recently, I had to recover my partition table with "testdisk", due to a foolish attempt to resize a partition.I recovered all partitions, with the exception of my root partition. I left that unallocated, then reformatted it with GParted, to be of a larger size.All data has been recovered & the PC works fine, just as it always has.The wierd thing is that the original "root" partition seems to co-exist on the same partition as my Fat32 data(???)GParted shows my root partition as almost full, when it should only be about half full....then my Fat32 partition shows empty, when it should be about 3GB full. Root should only be about 5GB, not almost 9GB.I believe that my mtab & fstab are corrupt relative to the partitions that GParted lists, and need to be fixed. However, I don't know where to start.?
View 9 Replies View RelatedSince installing 10.4 I've been having startup problems: I get a message requiring me to press S to mount various disks. Something which I've never really understood is: what is the relation between fdisk and fstab?At present fdisk gives sda1 and sda2 as my Linux partitions, sdb1 and sdb2 as my Windows partitions. fstab has:
/dev/sda1 /media/winboot ntfs
/dev/sda2 /media/windata ntfs
/dev/sdb1 /media/sdb1 ext3
/dev/sdb2 /media/sdb2 ntfs
/dev/sdb5 /media/sdb5 swap
which looks a bit sus to me. Am I supposed to make my fstab match fdisk, or does fstab modify the result of fdisk when it boots, or what?
I made a mistake in my fstab. I know what the problem is and how the fstab needs to be changed. However, since the system will not boot I'm having diffeculty getting in to edit it.The system is running Ubuntu 10.4 64 Bit with LVM2.I have both 10.4 64Bit Server and 10.4 32Bit Desktop cds currently and could burn others if needed. With 32Bit Desktop I'm able to get to a live cd prompt but my hard disks are not mounted.if I try mounting /dev/sda5 to a dummy directory I created it tells me it doesn't know the type of 'LVM2_member'.
View 5 Replies View RelatedI have a router that supports NAS; that is, you can plug a USB drive directly into the router, and it becomes a Windows share. I can manually mount the NAS share and use it properly. But, I would like to have it automatically mount on startup. The main reason for this is to assign it a proper mount point so that I can access it from the command line, since I'm having trouble doing that after I mount it manually.
To mount it manually, I go to Places > Connect to Server, select the "Windows Share" service type, and enter "//192.168.1.1/USB_Storage" as the server name. The server name is supposed to be "//readyshare/USB_Storage," but that does not work, so I used the IP address.
I would like to mount this drive at /mnt/readyshare. So, I followed (I thought) the instruction in this document. I created the directory /mnt/readyshare I assigned myself a samba password with smbpsswd I created a group "readyshare" with the GID 1010 I created a .smbcredentials file in my home directory I modified my /etc/fstab file.The .smbcredentials file reads:
Code:
username=<my username>
password=<the password I created with smbpsswd
The line I added to my /etc/fstab is:
Code:
//192.168.1.1/USB_Storage /mnt/readyshare smbfs iocharset=utf8,credentials=/home/<my username>/.smbcredentials,dir_mode=0775,gid=1010 0 0
But, no dice. The share does not mount.What am I doing wrong?
I have UBUNTU 9.10 Karmic Koala over Thinkpad R-61i. Whenever i boot my system i have the following message waiting for me,

Press Esc to enter a recovery shell
And once i press esc, my UBUNTU loads properly.

I recently added myself a harddisk with one big ext4 partition on it. I tried to add it to my fstab file like so:
Code:
UUID=c41b529d-77ee-427c-82b3-dff16f2123a2 /media ext4 rw,user,noexec 0 2
But it is not doing what I intended, which was the partition showing up in my Places menu. It also doesn't appear in my /media folder. How to alter the command above so I could have the harddisk open and writable in my Places folder just like my system harddisk?
I am not sure not to finish this line
UUID=d283b277-5df4-4e83-80b1-6021f2fe8272 /media/Label ext4
it is for storage
It looks like my problems with Error 15 are because I have UUID entries instead of root entries.
How can I access menu.lst and fstab using a live cd so I can edit the entries?
It looks like these files are on sda1.
I have UUID entries for USB devices in fstab in my Ubuntu 10.10. I assume this is because I have upgraded my Ubuntu's since 8.04. Each time I boot, I get a message saying it cannot mount the devices even though they are present. I have to skip mounting in order to complete the boot process. I also have two filesystems mounted at Root ( /). See later post in this thread.can I safely remove these entries from fstab and have Ubuntu automount the devices? If I do so, will this get rid of the messages at boot time?

I am using my NAS with settings in fstab, but then I have only 4.4MBytes/sec.
However, when I open computer->Network ->Windows-network->WORKSPACE->CH3MNAS, then I have a speed of 18MByte/sec.
I notice a directory ~/.gvfs/volume_1 op ch3mnas... but when I restart the PC, this directory is gone.
It only is there after I use Nautilus first.
Also, I see some directory called smb://ch3mnas/volume_1
Now I am totally confused... how to get the fast network speed automatically at boot of my PC?
WHy is this hidden inside ~/.gvfs/.? ... I prefer something like /home/nas
