Every time I attempt to transfer over a large file (4 GB) via any protocol, my server restarts. On the rare occasion that it doesn't restart, it spits out a few error messages saying "local_softirq_pending 08" and then promptly freezes. Small files transfer fine.
Relevant information:
Ubuntu server 10.10
Four hard drives in RAID 5 configuration
CPU/HD temperatures are within normal range
This problem is not exclusive to Ubuntu, I've experienced it in Windows and OSX as well, but it seems that almost every time I transfer a large number of files (i.e. my music collection) between my desktop computer and laptop via my external hard drive, I end up losing files for no reason. I usually don't notice the files are missing until later on, because I am never informed of any data loss. Now, every time I make a large transfer of files, I just do it two or three times to ensure that I don't lose any files.
View 2 Replies View RelatedI want to transfer an arbitrarily large file (say >20GB) between 2 servers. I have several considerations:
Must use port 22 (ssh) because of firewall restrictions
Cannot tax the CPU (production server)
Memory efficiency
Would prefer a checksum check but that could be done manually
Time is not of the essence
Server A and Server B are on the same private network (sharing a switch) and data security is not a concern, Server A and Server B are not on the same network and transfer will be via the public internet so data security is a concern, My first thought was using nice on an scp command with a non-CPU-intensive cypher (blowfish?). But I thought I'll refer to the SU community for recommendations.
sometimes when transferring large files using scp between my desktop running maverick and other servers running Ubuntu, Debian or CentOS, I get the following error message: 77% 258MB 11.3MB/s 00:06 ETAReceived disconnect from xxx.xxx.xxx.xxx: 2: Packet corruptI've found a seemingly related bug report on launchpad here: but the provided "ethtool" fix did not help.

View 1 Replies View RelatedI've got a quadcore PC, 2gb ram pc running ubuntu 11.04 with samba set up on a shared folder - the plan is to share files and media between myself and my housemates. However, I do not have the router attached by ethernet, I am connecting to the router (in another room) by a d-link wireless dongle.
I can access the share without real issue from my windows laptop and other computers in the house share I'm part of, and I can happily transfer a text file here and there, but it seems to be anything over 20mb will not go. All the files I am trying to transfer are >1gb and it's driving me mad.
After some decent transfer rates of around 1mb per second it just freezes up. The screen attached to the actual server goes blank and the host becomes unreachable by ping.I'll be happy to provide any command results or anything to get this working. any assistance would be welcome!
I'm setting up a htpc system (Zotac IONITX-F based) based upon a minimal install of ubuntu 9.10, with no GUI other than xbmc. It's connected to my router (d-link dir-615) over a wifi connection configured for static IP (ath9k driver), with the following /etc/network/interfaces:
Code:
auto lo
iface lo inet loopback
# The primary network interface
#auto eth0
[code]....
Network is fine, samba share to the media direction works, until I try to upload a large file to it from my desktop system. Then it downloads a couple of percents at a really nice speed, but then it stalls and the box becomes unpingable (Destination Host Unreachable), even after canceling the transfer, requiring a restart of the network.
Same thing when I scp the file from my desktop system to the htpc, same thing when I ssh into the htpc, and scp the file from there. Occasionally (rarely) the file does pass through, but most of the time the problem repeats itself. Transfer of small text files causes no problems, and the same goes for the fanart downloads done by xbmc. I tried the solution proposed in this thread, and set mtu to 800 in the interfaces file, but the problem persists.
I'm experiencing connection problem when transferring a large file from Windows 7 (Home Premium) to my Ubuntu 11.04. The transfer starts, but after a couple of seconds the connection drops and all the shares are unavailable. I'm also unable to connect to the server over ssh, and the only thing I can do to restore the connection is to reboot the server. The strange part is that this was never a problem a couple of weeks ago, and I've not done anything to the setup on either machines besides installing security updates.

The whole setup is extremely new (the cards only recently became available for purchase.) We've finally worked with Emulex to get the cards functional, and we are ready to some stress testing to the SAN. My question now is, is there a good tool I can use to generate a large amount of traffic to a LUN? The Wintel team used a windows-only tool that showed an average of 6gigs/second throughput, so I need something that can generate very large files and simulate a consistent throughput to the LUN. I found iozone, but I'm having a devil of a time with it.

View 7 Replies View RelatedI've resolved to move onto Ubuntu, but I haven't done so quite yet. One question that sprang to mind was the transferral of files from the Windows OS to the Linux OS on the same machine, if it's possible. I'm thinking something like the dual partition, though I suppose Copy/paste wouldn't work.
Another possible solution was using dual partition and then Windows SCP, but everything I've read on the topic indicates that SCP works by finding the (different) host address of the computer; thus it would read my machine as one, even if I'm running Ubuntu on it as well.

View 6 Replies View Relatedwhen I try to transfer files between flash drives, it starts to copy normally and then after few seconds it starts to lag. Transfer rate drops with each second by 0.2 MB down until 5 MB/s where it completely hangs. This happens to every single flash drive I put in and this is annoying because I have external HardDrive connected over USB port and I keep all my data in there, so when I try to transfer the files from the hard drive to the flash drive - it lags and hangs. Same thing if I want to copy from internal harddrive to flash drive. Although everything is fine when I copy from the flash drive to the internal harddrive and everything is fine when flash drive or the external harddrive is alone (no other flash drives or something is connected).

I have two different Linux operating systems (on two separate partitions) on my laptop. One is open SUSE and the second is PCLinuxOS and I frequently have to update files and folders from one to the other (the consequences of trying to keep both current!). When I am using openSUSE and want to access folders/files on the other OS, openSUSE asks for SU authorisation to access the other . . ./home file. Until recently, I could open ALL of the folders on the (other) /home file but now I can open some folders but not others. The Dolphin screen shows a warning at the bottom that "Could not enter folder /media...... " ! I can then only access the folder by going into the menu and using the 'File manager -Super User' mode ..AGAIN.
I suspect this action is necessary because I have had to previously open these specific folders in 'Root mode' to be able to 'paste' the moved file! I would like to avoid this (double) 'messy' action - how to change/avoid this My system is a 32bit openSUSE 11.4 with KDE 4.6.0 and the 2nd OS is also KDE 4.6
I am using the diff command with the -r option, to compare a large number of files and files in subdirectories. My main interest is to find out which files have been changed, and not what the actual changes are, and since a lot of files has been changed, it would be a lot easier to view the file names only. Is there and option for diff that might do this, or does there exist a similar tool/command that could do the job?
View 1 Replies View RelatedI downloaded Amarok 2.4 today and am attempting to use it to sync my music to my iPod Touch. .mp3 files transfer perfectly, but for some reason any .m4a file is being reassigned a .mp4 extension and being relegated to the 'Video' app on the iPod. I do realise that an .m4a is just .aac audio in an mp4 wrapper, why Amarok and/or the iPod is deciding to treat them like a video instead? It's doing it both to my own ffmpeg-encouded .m4as as well as unprotected .m4as from the iTunes Store (relics of my time on Windows). Anyone know what might be going on with this?

View 9 Replies View RelatedI've discovered that Dolphin seems to lose random files when copying many large folders.
I first noticed this a few months ago when I tried to copy my music library from one folder to another on the same HDD. It consisted of around 600 folders and 6500 files. During the copy there were no errors but after the copy I found that some of the newly copied folders were missing files. I put it down to human error or a glitch.
Yesterday I tried to copy 13 folders containing rips of some of my DVDs. Each folder basically had one film of either 700MB or 1.4GB. Again no errors showed up during the copy but I found 3 of the newly copied folders were empty.
It's not so critical with music or films but I can't afford to lose work data like this.
Has anyone experienced or seen a similar problem with Dolphin? I'm going to have to do some more extensive testing but this is not good.
The first time I noticed the problem I was running KDE4.3.4 (I think) and now the latest was with KDE4.4.0.

I have Ubuntu on both my laptop and desktop machines, both are connected to the same network. I back up the laptop to the desktop by running the following on the laptop:
rsync -avv --stats /home/alisdt alisdt@xxx.xxx.xxx.xxx:/home/alisdt/laptop_backup (with the IP address of the desktop instead of the many x, obviously). Whenever rsync hits a large file (greater than a few MB), the network use rapidly drops to ~60KB/s (that's kilobytes not bits). When I copy the same file to the same place using scp, I get > 500KB/s throughout the transfer. Things I've tried:
* mounting the desktop home dir on the laptop using SSHFS -- a simple file copy is fast, rsync is still slow
* ditto with NFS
* rsync --whole-file option, in case the delta-transfer algorithm was choking on large files
* rsync --inplace option
* HPN-SSH (http://www.psc.edu/networking/projects/hpn-ssh/) to enable dynamic window and unencrypted bulk transfer, just in case it was some ssh bottleneck I think it's either an rsync application problem, or a network problem that is only affecting rsync. Any ideas, or other ideas of what I can try to debug? In case it's relevant, I'm using 9.04 on both machines. (A standing bug prevents me from upgrading the laptop, and I haven't bothered to upgrade the desktop).
I am trying to move a large amount of files (over 30k and 86GB) to another HDD but I get a Augment list too large error?? I tried rsync, cp, mv and still the same error
