Hardware :: Local Hard Drive As Cache For Nfs Mount Writes?
Jun 18, 2011
I had the idea to cache writes to my nfs filesystem on my local hard drive.
It seems CacheFS exists to cache reads, but not writes to nfs.
I would imagine that if I could cache writes to my nfs on a local drive I could have a fast system, but keep all my files where I want them on my network.
I'm thinking about this because I am planning on buying a SSD, and I would imagine if I could set things up this way the system could be lightening fast while keeping things on the network. Currently if I copy a large file (hundreds of MB) it is quite slow, with an SSD and caching, I would imagine the copy could be very fast.

I don't understand this error nor do I know how to solve the issue that is causing the error. Anyone care to comment?

I know JohnVV. "Install a supported version of Fedora, like Fedora 11". This is on a box that has all 11 releases of Fedora installed. It's a toy and I like to play around with it.

I run a headless Ubuntu 8.04 server, which acts as a web, email and file server. I am sticking with 8.04 as it is a LTS release and will upgrade to the next LTS when it is released.
I have two external USB drives, that I need to mount at boot. I have been using /etc/fstab up until now, with the following entries:
Code:
However, as I gather from doing searches is quite common, occasionally I get an error during boot (causing the system to drop to a recovery shell) because the USB drives take time to wake up and the system hasn't found them by the time it reads /etc/fstab.
From doing searches, it seems there is nothing you can do to fstab to fix this, so you need to mount them using an rc.local script instead, using:
Code:
The problem is, as I have two USB drives, their /dev/sdxx location changes between boots. I thus want to use UUID codes as I do in fstab, however I haven't found anything about this.
Does anyone know how I can use the mount command and UUID to mount a drive in rc.local and what options I have to use the mount the drive with the same options that I am using in my fstab entry? Obvisouly, I can't refer back to fstab using the mount command, because then I will still get the boot error issue if they are listed in fstab. And there is no space internally for the USB drives as there is already two internal drives.

I was trying to figure out how to get my network drive to mount as a local drive on my computer. This was back on 9.10. Since I've upgraded to 10.04, my boot process halts and tells me (paraphrasing) /shared is not ready to mount. To continue, pres S to skip or M to manually mount the drive.
Well, I have it mounting now through GVFS and I don't need this in my startup anymore. Frankly, it's just annoying that it won't boot into Ubuntu right away. So, what's the startup file I need to edit to remove the attempt to mount the network drive?

I have a computer, the one I am on now, with Ubuntu 10.10, it should be completely updated... and I can network with other computers, I can access Windows XP and 7 shared locations on other computers, and I can also get Ubuntu on other computers to access this computer's shared files.What I can't do, however, is share my hardrives that are on this computer, I have tried sharing them in /media/ and etc, but it is not working, apparently you have to mount them in some mystical way.
Another problem is getting Windows machines to access Ubuntu computers on the network - which I believe is a Windows problem, so I can figure that out some other time, but importantly, I want to be able to share my hardrives over the network.
If someone can give me some instructions to mounting and sharing hardrives(internal), and even my DVD-Drives, and portable USB devices, would also be fantastic - since, in Windows you can just right click, "share", and it's done.. It is a very useful thing to have, and I don't want to use Windows on this computer anymore, but I have no choice, really, if I can't share my storage to the other computers.

I am making backups and I need to make a cron job that mounts a 2nd local hard drive.
It is not listed in my fstab file and I mount it manually in nautilus (having to type a password). It is designated as /dev/sdb1 and /media/repo when it is mounted. Can I get cron to mount it and then add the password or do I have to add it to fstab?

I'm new to Fedora. Is there an instruction manual. I'm using Fedora 14. I found under documentation a manual for musicians and amateur radio enthusiasts, but not for regular users. I'm using a black widow, which is a holder for hard drives that connects thru USB. I'm trying to mount it. The file system is Ext4.

I have got 2 hard drives running one one of my computers which i am running as an server. I was using Ubnntu Server which is good but i have decided to change the way that i am going to use the server and have installed Xubuntu over ubuntu server. However in the installation the hard drives shwn when it asked where i would like to install the operateing system. It installed sucessfully and is working but it cant mount my other hard drive which has all of my data on it.
I had tried mounting it throught the command prompt and had no success. After which i have checked if the the toher hard drive is being reconised by Xubuntu and it is as sdb1 but i caqnt mount it and get to my data. I hoped that i can try and put in my ubuntu live cd and see if it can pick the seoncd hard drive up and mount it which it has not been able to.
I have 2 20 gigabyte hard drives atm the moment and i am not adding the others until i can get to all my stuff again form the other hdd.

I want to pull a few things off this external hard drive I have that is an ubuntu install from last year. However, my mac won't recognize the file system and mount it so I can pull the few files I need off of it.
What's the trick to getting a mac to find an ubuntu hard drive?
My other option is removing my laptop hard drive, installing the ubuntu one, opening ubuntu manually, burning the information I need to a CD, or a usb key, and then removing the ubuntu hard drive, and reinstalling my mac osx drive to the laptop bay.

I am trying to mount a hard drive it shows up as /dev/sda1
I can click it and mount it via the GUI but I need it mounted for this script and do not want to have an extra step of doing it manually
I have tried (also tried sda vs sda1, no differance)
sudo mount /dev/sda1
sudo mount -t ntfs/dev/sda1
sudo mount -t ntfs-3g/dev/sda1
I know the drive is sda the only partition on it being sda1, but either I get an error saying it couldn't be found or I simply get no response depending on how I alter the code
Oh also the drive shows hpfs/ntfs 0x07 in the disk utility

I have just installed Oracle Enterprise Linux. (which i believe is build on redhat). This copy of linux is installed on one hard drive, in the system there is another hard drive and also an SSD.
How can I mount the SSD and other hard drive so that I can read and write to them?
Unlike Windows, they dont simply appear under 'my computer'

I bought a "WD My Passport Essential 320 GB" usb drive. When I plug it in (suse 11.2 x86_64 gnome version), it won't automount, a message appears ".../dev/sr2 is not a valid block device", I can not mount it manually neither Don't have a clue how to proceed in solving this issue. The drive is a bit strange though, it has some software on it for protecting data, which I wont need, but can't get rid of it neither. However when I connected it to my laptop running ubuntu 9.10 x86_64, the drive automounted ok, so I guess I must be missing some additional software on my suse. The drive was initially NTFS formated, but I did reformat it to FAT with ubuntu.

I've added a 1TB hard drive as a second hard drive on my PC, mostly because my home partition is full of music and movies, but I am unsure of where to mount it (or what to mount it as). "Yast Partitioner" suggested /tmp /srv or /localI basically want a storage solution for media files which can be accessed by multiple users (including a windows PC using samba)

I am having problems mounting an iso on my external hard drive. I do not want to move it onto my linux partition because it is 3.6 GB. I have a directory made (/media/iso) that I would like to mount it in, but if that doesn't work then I don't care where it goes. After I mount it I want to be able to run it using Wine, but that will come later. For now I just need to get it mounted. And, of course, I am fairly new to linux/ubuntu.

I've been checking the Forums and I can't find anything similar to my problem yet. I have 2 external drives that my UBUNTU 9.10 doesn't recognize, although I can see them perfectly in Win XP.I was using them in Ubuntu until 2 weeks ago, when this problem started and I can't find a way to see/mount them again. GPARTED doesn't find any of them; and when aply fdisk -l, can't see them either (only my internal HD).

I run 10.04 lucid in a laptop with EXT4 as filesystem, and I tried to mount an external hard drive from a Windows that, obviously, uses FAT32. Its the first time I try to mount a hard drive (external) since the upgrade to 10.04. Do I have to download some packages via synaptic? If not, what do I have to do?
Plus, I have run
Code:
sudo fdisk -l
and this is what I get

Installed ubuntu 10.4 on a formatted hard drive IDE. desktop has two other drives , one SATA drive and one SCSI drive. SCSI drive has windows.
Both windows and ubuntu load fine through GRUB2 etc
I had installed WUBI before on the SATA drive and then i uninstalled it.
problem is that when i log in to Ubuntu i see on fdisk
But i cannot access the SATA drive /dev/sda i tried mounting the drive but i get an error saying this is mounted as /dev/sdb5
How do i mount the SATA drive to get access to the drive ? i messed around with this drive when i was using WUBI. i.e. tried to mount it to recover grub but never got it working. Now somehow it seems that this old mounted drive is messing with my current Ubuntu install.
How to recover my fstab is shown below:
Changed the connect sequence in BIOS and mounted the volume using sudo mount /dev/sdb1 /media/sdb1

Windows XP Laptop hard drive is stuck in a hibernated mode. Will not let me access it through Windows, period.
I loaded Ubuntu Live on the suggestion of a coworker in order to retrieve my important files by hooking up the Windows HD through a USB adapter (Inland).
Ubuntu recognizes the 160GB HD, but refuses to mount the drive because "Windows is Hibernated." I Know my disk is hibernated, I need a way to get my important files from the drive...
(Screen Shot Attached in .jpeg format)
I know very little abount Ubuntu so please keep that in mind with your gracious replies.
