General :: Mount - Disable Read And Write File Cache On Partition?
Feb 8, 2011
How do i disable the linux file cache on a xfs partition (both read an write).
We have a xfs partition over a hardware RAID that stores our RAW HD Video. Most of the shoots are 50-300gb each so the linux cache has a hit-rate of 0.001%.
I have tryed the sync option but it still fills up the cache when copinging the files. ( about 30x over per shoot :P )
/etc/fstab:
/dev/sdb1 /video xfs sync,noatime,nodiratime,logbufs=8 0 1
Im running debian lenny if it helps.

I want to simply mount an ext4 file-system onto a normal mount point in Ubuntu (/media/whereever), as read-writable for the current logged-in user, i.e. me.
I don't want to add anything into /etc/fstab, I just want to do it now, manually. I need super-user privileges to mount a device, but then only root can read-write that mount. I've tried various of the mount options, added it into fstab, but with no luck.

I have Intel X25-V SSD connected to linux machine and its status is shown as "[sdb] Write cache: enabled, read cache: enabled" in dmesg. I knew we can disable write cache using hdparm. Is there any way to disable read cache and is this read cache present on SSD ?

I have problem with umounting usb flash drives. When I insert usb flash and copy big files to it ( 400MB ) copy process is quick ( system use cache to store files ). After this when I umount this drive, after 1 minute I got error that this drive cannot be unmounted ( because cache is not stored in drive, umount time limit I think ). How to disable write cache to usb flash drives, change its size or change umount timeout.

I'm testing OpenSUSE 11.3 on a server and I'd like to disable the write cache on all of my drives. In Ubuntu Server I was able to accomplish this with hdparm by adding the appropriate settings to /etc/hdparm.conf
As far as I can find the only thing that OpenSUSE offers is /etc/sysconfig/ide which allows you to force particular DMA modes. I could just put the hdparm commands in /etc/init.d/boot.local but I'd prefer to do it the right way if there is a right way to do this in OpenSUSE.

I saw a lot of people asking this question on the net and most (if not all) answers points out to disabling journaling on that partition, which is not always a good idea.
So here is 1-2-3 style how to mount HFS+ partition in Ubuntu, so that you are able to write on it:
1) sudo apt-get install hfsplus hfsprogs hfsutils
2) mount -o force -t hfsplus /dev/XXX /mnt/v

I try
mount -t ntfs -o rw /dev/sdb1 /mnt/exthdd
it doesn't give me any response so I presume it succeeded but when I try to touch it, it tells me it's a read-only file system

I have installed a cable that connects from the CPU's SATA motherboard connection to a removable drives' ESATA connection.I would like to be able to swap drives on the ESATA connection and have all users be able to read and write to these drives.I have created the directory /archive/ where I would like the drive(s) to mount.The drives are all formatted Fat 32 - but in the future I may use HFS for formatting.When I used the command (as root):mount /dev/sdc1 /archivethe drive was mounted (but read only)What can I use in my /etc/fstab file that will allow drives to be mounted and unmounted by all users on the system? (both reading and writing)Also, will I be able to mount and unmount these drives without shutting down? or will I need to reboot every time I want to change drives?

sudden of all all USB drives and sticks I put into a PC will not mount with read/write permissions (they did before). I can still copy to them, but only when I am root. I am on Maverick I've noticed though that if I run disk utility, then UNMOUNT the partition, Check File System, Mount the partition back, I get read/write access..

I have a text file that contains a single word and I want to write a bash script that will read the word from the text file... The following is my incorrect attempt, as it assigns the name of the textfile to the variable as opposed to the word stored within the textfile:(assume I have a text file value.txt that has its contents a single word, say wordone)
Code:
#!/bin/sh
for f in value.txt
do
echo $f
done
so the output of the above script is value.txt, however I want it to be wordone.to summarise: how do I assign the value of the word contained within a textfile to a variable?

My Canon PowerShot A470 + CHDK can write to SD-cards that are "locked" (the lock switch is used to make the card bootable), but GNU/Linux
`/dev/mmcblk1': Read-only file system
(I'm using "Texas Instrument 5-in-1 Multimedia Card Reader")
So I have to switch that switch on and off again and again. ("unlocked" to write to the card in Linux, "locked" to boot the camera from it).
How to force locked card to be writable in GNU/Linux?

I am running Karmic x64 on a HP laptop that has a cd/dvd burner. I have a r/w cd with files on it and I wish to add/remove files to it. After it mounts automatically on insertion, I unmount it and remount with:
sudo mount /dev/sr0 -t iso9660 -w /media/cdrom
(I tried assorted other hare-brained things also) but it always says that the filesystem is read only. Do I need to use a different device than sr0? Is it even possible under Ubuntu?

We have a network with several computer. We have two file servers (don't ask why) an Ubuntu and an XP as well as many clients. Setting shares on Ubuntu was easy and all clients can see them read and write. but I can't get the Ubuntu clients to see the SMB shares on the XP properly. This is my fstab:
Code:
//192.168.0.100/resources /media/resources smbfs iocharset=utf8,credentials=/home/boss/.smbcredentials,dmask=775,gid=1009 0 0
//192.168.0.9/summer /media/summer smbfs iocharset=utf8,credentials=/home/boss/.smbcredentials1,dmask=775,gid=1009 0 0
[Code]....

I don't want to have to download the kernel source and uncomment out CONFIG_UFS_FS_WRITE=yes and build a custom kernel ever time I update the kernel. Is there a better way? Like when Ubuntu.deb repositories claim a stable kernel is there an auto config script when installing from synaptic -or- aptitude? Like any way to add this one config opt to .deb kernel W/O building custom one from source?
