View 2 Replies View RelatedI'm seeing sustained disk writes of about 2 MB/s in the indicator-multiload indicator in Unity. I determined that it is writes on my 500GB HDD on /dev/sdb. This behaviour started after I used Gparted to create a single 500GB ext4 partition and also selected that it should be formatted to ext4 in Gparted.
Is this usual? It also survived a reboot.. I assume that it is the full formatting taking place in the background?
I saw no activity using pidstat or iotop. Only using vmstat -d revealed the writes.
Read/writes are slow on NFS.How can we diagnosing the issue, what commands are used for the error finding

For each write, I would like to know the time, date, process id, user, file position, byte count, and the data written.
I could use this with a script to replay the writes to a backup of the original file, and reproduce the file contents as they were at a point in time.
I have two ntfs partitions I use to store music and data. I've been using them in all my linux boxes without any problems. Simply use Ntfs-3g with noatime and everything works great.
However, since the update to OpenSuse 11.3 writing to my NTFS partitions takes FOREVER. I've specified noatime, relatime and norelatime successively without success. The partitions have plenty of space and are defragmented.
When copying large files, It starts fast at first, but in the last hundred MB it slows down to about 1.5MB/s. Even after the transfer is supposedly done, the HD led remains on and all other read/write activity involving the partition is completely halted.
This can take between 5 minutes to 10 or more depending on the size of the file. When copying several small files, (100 MB or less) it starts at about 1.5MB/s from the beginning.
I have the latest versions of fuse and ntfs-3g installed
I'm using 9.10 Desktop 64bit on a Dell Latitude D830. I have 4 gigs of RAM and a 7200 rpm sata hard drive. Everything works pretty well, video, sound, and network. Flash isn't as smooth as in Windows but I assume that's a Flash/64bit thing and not necessarily an Ubuntu thing.
However, one area of performance still lags far behind my Windows XP experience, and that's disk writes. For instance, when I'm copying a large amount of information from a USB drive or from my Windows partition to my native partition, I can barely switch windows until the task is complete, nevermind trying to surf the Web. I thought that that might be related to the slow performance of the ntfs driver, but recently I have been doing a lot of work with VMWare, and I get the same result when trying to pause virtual machines - it writes a largish amount of information to disk in a short amount of time and I can't do much until it finishes.
Here are some things I looked at based on other threads to try to debug my issue:
~$ sudo hdparm /dev/sda
/dev/sda:
multcount = 8 (on)
IO_support = 1 (32-bit)
readonly = 0 (off)
readahead = 256 (on)
[Code].....
That disk read speed is a little faster than average - several more tests showed it hovering around the 66 MB/sec range. Of the other info, I see that UDMA is on which I understand is good, but if there is something else there that I should fix I don't see it.
I know that my computer can handle these tasks (at least the vmware stuff) without such a significant interface slowdown because in XP I did it with less RAM than I have now. Is this just the way that the linux kernel scheduler fails to account for UI needs?
We are graphing various system parameters using Cacti. One of our graphs shows hard drive reads and writes. A question came up: why do we need this graph?

I'm using Ubuntu and recently bought SSD. I moved /tmp to ramdisk and did some other tweaks to avoid wear. But I was wondering if there's a way to pinpoint hotspots in filesystem where files are often written. For example webserver's log directory with many appends every minute or user's download directory where he downloads gigabytes of stuff only to be moved elsewhere soon after finishing.
I came across inotify which could probably do the trick but it seems it'd require lot of scripting which I'm not very familiar with

I'm having a really annoying problem with disc activity on my desktop system. Basically, if anything is writing a large amount of data to the hard drive (say, 10MB or over), the machine basically freezes solid. The mouse goes jittery (you move it and it takes a second then moves in one big leap).
For instance, if I try to image a USB hard drive to a file:
# dd if=/dev/sdh of=usbdrive_dump bs=1G
Effectively this works in two portions: it reads 1GB of data to RAM, then blats it out into a file. The machine is perfectly responsive while the USB drive is getting thrashed, but locks solid when the internal SATA drives are in use. Writing to USB HDDs doesn't seem to have the same effect -- I can copy 1GB files to/from them all day long and the machine is perfectly happy.
I hav Debian Sqeeze, and not knowing what I did, it suddenly starts to consider all pressing of e key as 0128. Also some other key, which I don't know currently. I use different layout, however it happens on others too.
View 2 Replies View RelatedI'm working on a project using CentOs 5.3 that uses a solid state drive (SSD) as the boot device. It is desired to configure it such that writes do not typically occur run-time but configuration files can be saved. There are 2 reasons we do not want writes to occur run-time. 1) Writes will wear out a SSD over time. 2) A system disruption during a write can cause a file system error.
View 3 Replies View RelatedI have Fedora installed on a netbook. I customarily mount several NFS shares on this machine, from both a desktop system running F11 and a small server running FreeBSD. On the server side the shares are write-enabled. On the server side the shares are write-enabled. In the past this has worked fine.
However since upgrading to F12, my configuration no longer works as before. Reading from the NFS shares is no problem, but as soon as I try to write to one, either in Nautilus or from any other program, including on the cmd line, all hell breaks lose. Nautilus crashes, and I am unable to remount the shares. Usually rebooting the client is the my only recourse.
There are no clues in dmesg on either the client or the server. In terminal trying to remount a "trashed" share I see this:
Code:
$ sudo mount -v venus:/media/disk8 /media./disk8
mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Sat Feb 20 17:34:59 2010
mount.nfs: prog 100003, trying vers=3, prot=6

The NFS versions under F11, F12, and FreeBSD are the current ones (all updates applied).
I have a fileserver running 10.04 server 64bit and samba. I connect it to my desktop which is 10.04 desktop 64bit.I have the server mounted on my desktop in fstab as://10.0.0.2/share /media/share cifs guest, uid= 1000.Up until 30 June 2010 it was all fine. Now when I write the server it is very slow e.g. 2Mbps though when I read I get >100Mbps so I think my network is still ok. If i use nautilus smb://10.0.0.2/share I can write at >100Mbps and also read at >100Mbps...So any ideas why the write speed via the fstab mount samba has started to go really slowly in the last couple of days?
View 6 Replies View RelatedI 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 run a website that a very steady flow of traffic and Im seeing recent issues that I just dont like. Server is 10.04.2 on a supermicro i7-950/6gb RAM with two 500gb Samsung F3 drives in a software RAID1 (1x5400, 1x7200) and for several weeks, its been running very well. Recently, Im seeing the server hang for 5-20 seconds. IOwait goes through the roof, nothing can write to the disk. Apache logs stop, redis fails to rebuild caches, mysql errors and then it continues and moves back to normal operation
/ is ext4, the kernel was 2.6.32-server-x64 but since updating to 2.6.38-server-x64, the issue has dropped from maybe once per 10 minutes to once per 15 minutes. 3 IOstat copy/pastes show this when it hangs.
Code:
Total DISK READ: 0.00 B/s | Total DISK WRITE: 0.00 B/s
TID PRIO USER DISK READ DISK WRITE SWAPIN IO> COMMAND

No smart errors or smart diags show any issues with any of the disks and kernel.log shows near nothing other than a process hang, 120 seconds about 5 days ago.
like my alias a retired person, and Its never to late to learn something½ve just installed Ubuntu and found a tutorial online about bash-script.Manage some, but I cant to this one:[Write a script that makes file executable and writes a message that it has been done.If I run the command > <scriptName> <fileName> , then the file fileName should be executable and then it should indicate that fileName have been executable.]
Ive read man pages up-n-down and search the web, and I think I should let the script use chmod and ls -l, but I cant get the hole picture here. Actually I have nothing to show up, so I hope someone could help me with some ideas or a soloution - just to the how it should look.This is my first post, ever, at a forum like this, so please be nice if I didnt follow any rules here, I dont know if you even will answer this post, but at least give me some clues, a skeleton-code ti be based on
Is there a way to determine the IO size that is being used for reads and writes to an attached storage device? I am trying to pattern the IO sequences to storage. I have seen mentions to max_sectors_kb but the notes indicated that changing this value did not change the IO size to the storage.
View 1 Replies View RelatedIs there already a program that reads multiple pipes or file descriptors and writes to the standard output (not splitting lines).Like cat, but reading all files simultaneously and preserving lines.It is needed to avoid coding of select/epoll loops or using multithreading in simple programs. Like "select loop for bash".
View 1 Replies View RelatedI have a 6 disk mdadm RAID 10 array of Western Digital RE3 drives. IOZone and all the other tools I have tried are showing pretty lackluster reads for a six drive RAID 10 array, in the area of 200MB/s. Writes are closer to what I'd expect in that area, around 340MB/s. These drives fly with an Adaptec RAID controller, but as soon as I stick them in an mdadm array, the reads just aren't what I'd expect.
I am using what I believe to be optimal settings:
-C /dev/md2 --chunk=1024 -n 6 -l 10 -p f2 /dev/sda5 /dev/sdb5 /dev/sdc5 /dev/sdd5 /dev/sde5 /dev/sdf5
-b 4096 -E stride=256,stripe-width=768
I have an SSD and I'm trying to set noatime to save writes. I didn't do this at the time of install, so I edited /etc/fstab later on. I noticed, however, that when I right-click on a file and view its properties, it still gives me a "modified" and "accessed" time. Did I do something wrong? Here is my fstab:

I have 3 computers. One running openSuse 11.3 with SAMBA and the other 2 are Windows 7 Professional boxes. I have the same user name and passwords for all three boxes.
From the Linux box I can access one of the Windows 7 boxes but the other won't accept my user name and password. The one that won't accept has Windows LiveID Sign-In Assistant installed. Apparantly that's an automatic install now.
I've read that there is a bug with the SAMBA libsmbclient [URL].
I tried updating via YAST but still end up with version 3.5.4-5.1.2 and this doesn't work.
this might not seem a big issue but I'd really like to know whether it's possible to stop Nautilus from unfocusing windows when pressing on an item in another windows and draging it to the first one. For example, I want to move a file from one window to another. I click the middle mouse button on that item and drag it to the first one which looses it's focus so often it's quite irritating.

Whenever I've gotten a new box, it's either been home-built or a Mac.Now I have a new Acer Aspire AS7551 laptop, and although I have not yet booted into Windows, it comes with a Windows 7 Home Premium license. I've been running it with Ubuntu 10.04 off a flash drive and everything works perfectly.
What I want to do: I want to wipe the disk, install Lucid, and run Windows in Virtualbox (for the sole purpose of watching some Netflix and learning a little bit about Windows 7). For the purpose of this question, please accept that I DO NOT want to dual boot.The problem: From what I can find, I can't use the "recovery discs" that came with my laptop to create a virtual machine. This is confusing, because it seems like I paid for a legitimate Windows license for use with this laptop.
Questions:
1. Would MS exchange my recovery discs for a regular install disc to go with my license code if I explained this to them?
2. If not, is there a source for Windows ISOs that I can safely use with my license? (I am aware that the legitimacy of that approach is questionable, but I am quite comfortable with the ethics since I paid for Windows 7, own the license, and only want to use it on the same computer.
3.If not,is there any way in heck I can use my recovery disc to create something Virtualbox can work with?
4. If not, how are all of you people getting your Windows virtual machines going??
(I have read that Acer is a major hassle to get a refund from for the "Windows tax" so I might as well be able to use it--this is MS' chance to win over a fan if only they will let me!)
I am a ubuntu novice. I am running 10.04 LTS on a Lenova laptop. Runs fine. Yesterday upgraded firefox and upgraded Java 6 from update 20 to update 24 so that I could use the Zotero bibiliographic program in FF. After the upgrade and restart, the windows title bar that includes minimize, maximize and close buttons has disappeared from all windows that I open except google chrome. If I open and app, or FF, or the dvd player, title bar is gone. I have noticed that Java updates have caused similar problems before but none of the prescribed steps seems to have changed my system
View 9 Replies View Relatedi am having some issues with dual booting my SL6.1 and Windows. The situation is that i recently acquired an old hard drive from a non-working computer of mine with Windows already installed (i know the windows is functional, as i tested it on my new PC with SL6.1 currently installed & everything runs fine)
The problem is that after editing the grub.config to include windows, windows will no longer boot after an attempt to install a legit version of McAffee anti-virus software which coincidently was only after the first attempt at running both OS's in a dual-boot fashion. Except past the windows start up screen before the dreaded blue-screen.
Which is weird because SL6.1 OS will still boot & works perfectly fine like always, so it doesn't really make sense.
My current setup is:
Disk 1: Solid-State:
Boot Partition
SL6 LVM1: Root Partition
Disk 2: Hard Drive:
SL6 LVM2: User, Temp & Swap Space Partitions (Different LVM to Root)
Disk 3: Hard Drive:
Windows 7 Professional 64-bit
My guess is its windows MBR. The reason i say this is because the Hard Drive contents of the Windows software still appears intact when accessing the drive from the Linux OS. I don't won't to go through the rigmarole of re-installing both OS's. So hopefully their is a relatively simple solution.
Last week I installed Ubuntu 10.10 on my system in dual booting. I had installed succesfully both but unable to see data files from windows OS. Though I have excercised the options in various resources available on internet/blogs. System takes about 03 hrs during installation process. I am also unable to configure Thunderbird.

I have a fresh install of CentOS 5.5. I am trying to browse to the Windows machines on my network (Places > Network Servers > Windows Network), but I get a blank window. I am able to ping the Windows machines using their IP address, but not by their name. What do I need to do to be able to see the Windows machines and also to connect to shared folders on these machines? So far I have tried starting SMB (via System > Administration > Server Settings > Services). I have also tried changing my smb workgroup to "WORKGROUP" (the default was mygroup which did not match my Windows machines.
