I have an Ubuntu 10.10 server and client. The server is stable, but the client crashes when writing to an nfs mount.The server has a software RAID, and I have tried every combination I can think of for mounting the share (udp, tcp, write size, nfs, nfs4 and so forth).
I don't have any security on the share, and it only appears to happen when writing to the share (so far). It happens fairly consistently when writing large files (over one GB). The copy starts to stall/start, then the whole interface freezes. I can't drop to other levels (ctrl-alt-f1), but there is still disk activity, and I had it beep at me after a freeze when I clicked several keys....
I'm trying to mount an NFS share from my Gentoo computer on my FC12 laptop, but every time I try to mount the share my laptop completely crashes. The end result is that I have an unresponsive laptop which switches from X to a blank screen and I'm unable to switch to any VT's or reset X. I never had any issues with my laptop freezing like this when I had Gentoo on it, but I'm giving FC a shot.
Server: NFS version: 3 Code: $ cat /etc/exports # /etc/exports: NFS file systems being exported. See exports(5). /mnt/OSX192.168.*.*(async,rw,no_root_squash,no_subtree_check) Running rpcinfo on the server (command run from client)
[Code]...
Anyone recognize these symptoms or know which log files to look in to begin diagnosing? Currently, I'm only able to transfer files via ssh, so I'd like to be able to do that properly.
I am working on a NFS server embedded on a PowerPC plateform (4650EX, 512Ram, 1 GB Ethernet) but i can't mount my exports folders from my client. Here are messages :-- server side :
$ tail /var/log/message Dec 11 23:35:45 canyonlands mountd[1345]: authenticated mount request from 147.138.27.17:620 for /mnt/ssd (/mnt/ssd)
Client is running Oracle VM Server 2.2.1 (kernel 2.6.18-128.2.1.4.37.el5xen). Storage is a NetApp 3210 (NFS configured to use TCP).
Iptables on client has udp and tcp ports 111, 2049 and the NFS server ports opened. Info retrieved using: rpcinfo -p NetApp
When trying a manual mount ...
But when using the proto=tcp option, it works ...
Stopping iptables also works (I can manually mount the share without using proto=tcp).
Is the mounting process somehow trying to negotiate first using udp which the Netapp doesn't respond and hence it fails by timing out?
Can I configure iptables such that I don't have to use the proto=tcp option? Or is there another configuration file I can tweak so that I don't have to use the proto=tcp option?
I am not able to configure nfs mounted disk for shareing samba. i have a server X. which configure samba for windows XP client this is done. now i have export X server samba share disk to mount Y server using nfs. this is mount and ok. but i don't share this disk using Y server samba configure.
I loaded the Pre-Release version of Ubuntu 10.10.1 32 bit workstation. It ran mostly fine for about a 2 months. Then I did an online update and it told me that I had to reboot. When I did, I booted to a splash screen and then a dead machine with a black screen where control-alt-delete does nothing, no disk activity, no mouse, no keyboard, totally dead. Had to hit reset button. I booted to a suse partition and hacked the grub entry to remove the splash and silent to get more spew at boot time. The last thing before the screen goes black is starting NBD client. I have my email and various directories on my central server so I need NFS. Is there a way I can hack my way to get it to boot even without NFS temporarily to possibly rebuild the nbd kernel module? I have looked at the /var/log/ syslog, daemon, debug, kern messages and gdm log files and don't see any indication of why it crashed. Where else can I look?
trying to create a "local network" by directly connecting an IBM Thinkpad with Debian Linux installed on it to an Alix computer running Voyager Linux. I'm following a "how to" I found to create a music server, hence the requirement. My issue is I can't get a static IP address to be configured on the Debian machine.I've trawled the net and have found the instructions about editing the /etc/network/interfaces and have tried to do this. First I tried to get DHCP working so I could connect the Debian machine to the net and this proved successful. I edited the interfaces file to look as follows:
# The loopback network interface auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp
Then I tried adding a static IP address to the machine. As this is a network purely between two machines I made up the IP addres and used 192.168.0.1 and used a NetMask calculator to give me a NetMask of 255.255.255.254 (I told the calculator there would be 2 machines on the network). I then edited the interfaces file as follows:
# The loopback network interface auto lo iface lo inet loopback
[code]....
I re-booted the machine (ifdown eth0 followed by ifup eth0 keeps saying that eth0 hasn't been configured - a problem there that I don't understand), but during boot up time it failed to assign the Static IP address to eth0 and made me go into SU mode. To fix it I simply replaced the interface file with the static IP inputs with the file that had the DHCP entries (I'd made a copy of the DHCP file), and re-started the machine. Everthing came up fine. So the first question is how do I get a static IP address to be assigned to eth0 such that whenever I shut down and restart the machine the static IP address is always loaded?
The second question is around creating the network via the cross over cable. From what I've found via Google, all I should have to do is create a static IP address on the Debian machine and a static IP address on the Voyager machine. Once they're connected by the cross over cable they should see each other. Is that correct, or do I have to do anything else?
We have 4 HDs on our server. One of them broke last night. I could see a message on the server and after restarting the S.M.A.R.T. on the BIOS was recognizing one HD as bad. After removing the failing HD, the server is now up and running. I do not remember how I configured the HDs. During the installation I had a few problems and I change a few times what I wanted to do. I am sure I had at least a RAID0 with 2 disks but I could have put all the 4 disk in the RAID having 2 disks as spare drives or I may have created another volume for the other 2....
dmraid return: No raid disks Code: $ sudo dmraid -ay -vvv -d WARN: locking /var/lock/dmraid/.lock NOTICE: /dev/sdc: asr discovering NOTICE: /dev/sdc: ddf1 discovering NOTICE: /dev/sdc: hpt37x discovering NOTICE: /dev/sdc: hpt45x discovering NOTICE: /dev/sdc: isw discovering DEBUG: not isw at 500107860992 DEBUG: isw trying hard coded -2115 offset.

Questions: 1-How do I find how the disk were and are configured? 2-How can I find what was on the disk that died? (Was it a spare drive or one of the 2 in mirror)? 3-What do I need to do now to be sure that the mirroring is working OK? (considering that there is a spare drive). Do I need to use a command to let ubuntu mirror the drive on the new one? 4-What do I need to do when I get a replacement of the broken disk? 5-What is an utility that can show me easily how the disks are configured and eventually makes a change.
I have Debian 7 running on RPi2 with Kodi. My NFS server is running on Slackware 14.1 which doesn't have full support for nfs4. I think this is causing some slowdowns/extra time when trying to stream video. Debian 7 by default mounts NFS as nfsv4, I would to like to disable this if possible. If so how?
Setting of my NFS as following and I am failed to mount client and get connected the both computer using Fedora 11; server ~(tower) and client (note book)

After making several attempt I cannot mount share on client. What I am missing here? OR is there problem with F11 with NFS server? While throwing everything including sink... I ran tcpdump on server while issuing mount command from client; I got following tcp dump.
Which reflect that client (computer - eagle) trying to make call on Server - tomcat but failing. We have a router which also server DHCP Server and issue IP but server has static IPs.
I've setup an NFS share on my Fedora 15 host of which Google'ing told me that it had changed radically from the old NFSv3 config. Ie. no more /etc/hosts.allow or /etc/hosts.deny files.....My current setup is this..../etc/sysconfig/nfs:
I have nfs-server installed and running on my Ubuntu 10.04 server. I have some directories exported. I can connect from my Ubuntu 10.04 PC using the commands: sudo mount taylor10:/data0 /t10/data0 sudo mount taylor10:/data1 /t10/data1 sudo mount taylor10:/data2 /t10/data2 sudo mount taylor10:/data3 /t10/data3
However, when I have my firewall on the PC enabled (Firstarter) I cannot make the mounts. I have ports 111 and 2049 open. If I stop the firewall, do the mounts and then start the firewall I am still mounted to the nfs shares. The connection is on port 2049. I have observed that when the firewall is enabled and I issue the mount command I get traffic on a random port such as 46694, 37022, etc. I have found instructions regarding editing /etc/default/nfs-common but they seem to control the port the server is listening on, not the port which the client is asking on. How do I lock down the port which mount and/or the nfs client is using to talk to the server to make the initial contact.
i have installed nfs server on my redhat machine.when i want to mount shared data from client(suse)machine the following error occur. "mount.nfs: mount to NFS server '10.3.31.146:/home/usbtest' failed: System Error: No route to host" both machines ping each other successfully.
How do I mount a nfs jfs2 filesystem from a aix unix platform to ubuntu client. When I issue mount aixbox:/jfs2fs /mnt on the ubuntu box I get mount: wrong fs type, bad option, bad superblock on aixbox:/jfs2fs, missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program) In some cases useful info is found in syslog - try dmesg | tail or so
Is there a package that allows ubuntu to mount jfs2 filesystems from other unix boxes?
I have the following problem:I have to networks in remote places.I have an opnvpn client in one network that connects to the the router (openvpn server).My question is,can i connect the network where the openvpn client is,throught the computer with the client to the other network.If yes,how? (please make it an idiot proof anwser because i have limited knowledge about iptables). I was thinking like forwarding (the router in the network with the openvpn client is also firewalling with iptables) the request of the ip class of the openvpn network to the computer with the client,which masquarades the interface
I have a Dell Inspiron 1720 running Ubuntu v10.04 with a wireless card.My desktop is a Dell Optiflex running WinXP.The desktop is connected via ethernet cable to a Linksys wireless router. Certain folders on the desktop are set for sharing. Up until early last week I was able to access the desktop folders from the laptop with no issues.Suddenly I am now getting this error "Unable to mount location Failed to mount Windows share" whenever I try to access the desktop folders from the laptop.I suspect an upgrade is the culprit, but not sure.
i'm trying to connect to the three other machines in my house but am having quite a hard time doing so. i've never had a problem in the past with ubuntu, but, with 9.1 and windows 7, things have gotten a bit harder. i'm running 9.1 and my roommates are running windows 7. i've installed, set up and configured samba and i can see the computers on my network, but any time i try to access either of the drives, it says unable to mount location: failed to mount windows share.
I have been trying to share folders from my main PC which is running Ubuntu 10.04. I have been able to figure out Samba enough to get my a couple of folders shared, but I have been unable to share any folders which are on my external harddrive. After entering the path in my smb.conf file they appear on the network but I am unable to navigate to them. When trying to navigate to them through the network folder on the pc they are actually connected to I get an "Unable to mount location: Failed to mount windows share" dialog box. On the windows pc I am trying to share with I get, "Windows cannot acces \Josh-Desktop ame of folder"
My smb.conf file looks like this:
That folders I cannot access are Music and Videos.
I have configured the remote installation of Fedora 13 with kickstart with nfs installation method. All work ok until I boot the Fedora 13 client system.
Fed13 client system receives the IP address from dhcp, receives the loader, loads vmlinuz and initrd.img from tftp, load anaconda, configures the network and dev eth0, mounts nfs server to load kickstart file, loads kickstart file (language...) but when it tries to mount nfs server to install from Fedora 13 installation tree it fails.
First, I thought that I had an error on my NFS configuration but I was wrong. I opened tty with ALT+F4 on the Fedora 13 client and I sew this error:
Code:
Is this a bug or can I modify anything to correct this error? How?
I'm working with OpenSusse 11.2. I installed and activated the NFS server via yast2. I exported the relevant directory via yast2 (NFS server configurastion) I'm trying to setup my Linux target to boot via NFS. The kernel boots up but fails to mount the file system. When looking on a capture from ethereal it can be found that the NFS server return error when client try to mount the /nfstest directory from this server. The returned error is 13
im trying to get a network setup i followed the instruction via gentoo wiki samba what i have done
[Code]...
then i did chmod 777 to the shared folders on both machines went into nautilus it sees the folder but it will not mount the folder showing the error msg:"unable to mount location failed to mount windows share" ive been searching unbuntu forums opensuseforums and google for an answer to this issue but as of right now anything that i have tried to do has failed and nothing seems to be working.
I have recently set up an ubuntu installation on an old PC. After some fiddling with both it, and the windows 7 machine, I have managed to share all of my drives. However, when attempting to access them from ubuntu, only 2 of the 4 hard disk shares will mount, with the other 2 failing with a Unable to mount location, failed to mount windows share error message.
So whenever I turn on my EeePC with Ubuntu 10.04 on it, the network crashes after like 10 minutes to 45 minutes. Every time. Of course I have that horribly <snip> bug where the WPA and even WEP on my laptop are buggy because of 10.04, but it did the same when I was on 9.10 (but like 3-4 times a day instead of many times an hour).
Yeah, so when I connect to the network with my laptop, the network crashes. The wifi still works, I can detect the wireless network on all my computers (my Ubuntu one, Windows 7 and my girlfriend's Mac), but internet does not work. I then have to turn off router/modem, and it starts to work again. Then, a couple of minutes later, if the Ubuntu laptop is on, it stops again.
That's annoying because I can't really use my laptop on the internet because I'll have to restart everything soon. I've tried setting to WPA and to WEP and it happens with both. Same goes if I set my laptop to a manual IP address or an automatic one. I did some tests to be sure, and the network works without crashing for days if my laptop is closed, so the problem really is with Ubuntu, and as I said, it kind of always did that, but it was tolerable before.
During NFS transfers my laptop crashes my entire wireless network. Laptop is a Samsung R20, Ubuntu 32-bit 10.04 with atheros AR5001 wifi and ath5k driver. What works: ->NFS is working. I have 3 other machines on wired connections that use NFS happily. And the NFS shares work fine if i plug the laptop into a wired connection. ->Wifi works. I can browse the internet and a large download (700MB) with bittorrent takes 8 mins and doesn't down the wireless.
What doesn't work: ->NFS and wireless together. Any NFS transfer over wireless eventually downs the wifi. Forl example streaming one 3mb mp3 in rhythmbox crashes wireless after playing for about 30 seconds. When the wireless fails it breaks for ALL computers and the only way to re=establish it is by restarting the router. Wired connections remain OK even when wireless is down (both from the same router).->I have a 64-bit desktop with wifi that also suffers the same problem but that doesn't matter so much since it also has a wired connection.
