My Debian Lenny server crashed today for some inexplicable reason, and now one of my machines refuses to mount NFS shares on bootup. Manual mounting works fine. It's just one machine; the others are still mounting normally.
View 2 RepliesI have multiple ubuntu machines and I connect to one through an NFS share. I have done this for a few years without issue. However, since re-installing ubuntu and upgrading to 10.4 I have a problem with my system hanging when the remote shares are lost.
Basically, I can power down the machine downstairs, and my main machine then has a fit. I can not open any folders in ubuntu, nor can I shut down. If I try and shut down the system hangs, last time it hung for 8 hours before I had to kill the power.
These are the lines in my fstab
I don't know what I've done wrong, or how I can prevent this from hanging. I have googled the heck out of this as well and can't seem to find an answer either.
I have been able to plug my iPhone in, and Ubuntu (10.04) has been able to see it immediatly. I was able to browse any pics etc. AND, I had the ability to SSH into it (Places>Connect To Server). In the connect to server dialoge, I clicked on the drop box and had several options including SSH. Now, there's nothing in the dialogue except "Custom Location". So, what happened? My iPhone no longer mounts and I have no SSH option! And I have not updated anything and made changes. I have tried 2 different cables and different USB ports.

Upon reboot, sometimes it would mount automatically and sometimes it would not. I have not discovered any specific pattern. It is very random. Sometimes it would go many reboots without mounting and on the next it would mount it. I tried putting timeo paramter, played with the parameters, but still have the same issue. My laptop is connected to a wireless network. When I do mount -a or if I go to Places everything mounts great. It just simply will not mount all the time automatically upon boot, and after wireless connection is established.
I have one hard disk (call her HDA) that contains nothing but a single ext4 partition containing a backup of all my important data. I did a clean install of 10.10 on my primary hard disk (call her HDB) and from there proceeded to the 11.04 upgrade. In 10.10, I was able to read HDA just fine. However after the upgrade, I can no longer mount this drive.
When mounting from file browser:

For some reason my hard disk has a block count greater than the size of my device. I've done my background searching on this and tried a command line utility I've never heard of before:
Code:
# sudo e2fsck /dev/sda
e2fsck 1.41.14 (22-Dec-2010)
The filesystem size (according to the superblock) is 122096646 blocks
The physical size of the device is 122096381 blocks
Either the superblock or the partition table is likely to be corrupt!
Abort<y>? yes
And this is as far as I've got. I'm really hesitant to start fiddling around and experimenting with possible fixes because the backup data on this drive holds a decade's worth of work for me and is extremely valuable (hence why I have a spare drive for backups). I really didn't think that the Ubuntu upgrade process would mess with this drive, seeing as the Ubuntu install was contained on an entirely different drive. Any safest way for me to recover this data? Data preservation is the #1 priority for me here. I need to copy all of this data over to my primary drive where Ubuntu is installed. After that, I can reformat this "broken" backup drive.
My Pug Server has worked faithfully for many years just sitting in a closet. It is designed wo that you never need to add a monitor or keyboard as it is administered through a web interface. Recently it had a problem with the motherboard and I had to replace it, but the machine is now working. However, it no longer is visible as a network drive on my Windows machine.Unfortunately I have no idea where to start looking to see what the problem is. I did attach a keyboard and monitor and logged on, but everything looks okay (I can see my files, etc.).
This is an old machine (c. 2003), so has an old version of Linux (I have no idea what version, or even how to find out). Since it is never meant to be used directly it doesn't have any GUI installed, so I have to do everything using command line.Does anyone have any suggestions as to how I can even start to determine what the problem is or how I can go about trying to fix it? At this point I would be happy just to get the files out and replace it with a newer NAS.
I am running Jaunty 9.0.4. I have go through a proxy to get out to the net. It was working. Sometime yesterday it was unable to resolve the proxy server. Can't even ping it. Other computers can. I even switch cables to no avail. What could block the proxy server? I can't even ping google.com Was it something I installed through add/remove software? Has anyone seen something like this before and even better has a solution or can offer a way to troubleshoot this? I can ping myself and the default gateway server.
View 1 Replies View RelatedI need to mount tmpfs partitions to /etc & /var and unpack archieves of this folders there. This task is complete working on Gentoo with monolite kernel & handmade initramfs script. But on fedora this method is like hacking. And not pretty for later upgrades, etc... I think, may be it is need to create script in /etc/init.d/ with high run priority. But this method takes many errors on boot.

View 1 Replies View RelatedI have several NFS entries in my /etc/fstab file. Each entry generates an error during boot (from /var/log/boot.log):mount.nfs: DNS resolution failed for macpro.dpc: Name or service not known mountall: mount /mnt/BaseLines [656] terminated with status 32
This occurs even if I specify an IP address in fstab rather than a host name. I was really surprised by that. The odd thing is that by the time the system is up, not only is DNS working as expected, but the NFS shares are mounted as expected. I'd just ignore it for now, accept that it prevents Apache from starting since some of the server's files live on the NFS shares (this is a development system). It appears that the DNS resolver isn't running when the mounts are attempted and that they are attempted again later, after the resolver is running.
I did an
$ sudo apt-get update
$ sudo apt-get upgrade....
How would i use LVM to add these mounts for example?

I have upgraded three machines to Fedora 13.
On all of them any attempt to mount an nfs drive fails with:
Code:
This happens immediately - within a few tenths of a second at most. It happens whether I use mount -a(mounts are listed in the fstab file) or a full mount command. It happens on both 32-bit and 64-bit installs.
Nothing appears in the messages log file on either the server or the client machine.
It was working in Fedora 12.
Iptables and ip6tables are both disabled. nfsd is running.
Hosts.allow and hosts.deny both exist on the client, but are empty. They contain nothing but comment lines.
I can ping the server and run ssh shells to it. I can open Web pages in Firefox.
The server is CentOS 5.4.
Is there way that you can specify the source address to use when mounting a remote share? I'm trying to test an application, and I need to be able to script a job that connects to a remote SMB server using different local IP addresses on the system. It would have 1 main address, and several aliases in the same subnet. The script would mount the remote server, transfer a file, then unmount, change IP, and repeat.
View 2 Replies View RelatedI`m using cifs to mount a windows 2008 server share. I`m mounting it read only and using an rsync script which works quiet nice.
Recently I couldnt mount the windows share anymore, i didnt know the account iam using would go inactive if i never logged in.
Just where does cifs write a log if it can`t mount a windows share? If I knew where it is it would also be easier to find the reason if it doesn`t work.
I have set up an NFS server on Fedora 13, and I am connecting to it with Fedora 13 and Ubuntu 10.
On both clients the command
Code:
works fine. On Fedora I can get into the directory with Nautilus and have read/write permissions as specified in /etc/exports on the server, but on Ubuntu I can only get into it from a sudo'd command line.
The ownership of the file on Fedora is "nobody" and on Ubuntu it's "user #500", with only people in the "500" group having access to it.
Obviously the permissions can't be changed on the client, but with the Fedora box being able to read/write to it with no problems I'm not sure what else I can do on the server to let normal users on the Ubuntu box read it.
I have a Buffalo Drivestation (model HD-CELU2, 1tb) attached to my network.From my ubuntu desktop I can go to the menu, select "connect to server", put in the ip and share info, and it mounts perfectly.I can open the share and browse eadwrite, but when I try to mount it from a terminal or within fstab, it will still mount, but I cannot see any files that are on the drive. I have about 12gb of data on it, but like I said when I mount it using "mount -t cifs 192.x.x.x/share blah blah blah" I do not see any of the files.If I do a df I can see that the drive has files on it based on the free space available, but if I do an ls nothing shows.

Our organization uses OpenSuSE servers (NFS/LDAP/SAMBA/more...) and are in the works migrating all the workstations for users to SuSE from Windows as well.
I like how in windows the mapped network drives are all listed in My Computer. OpenSuSE has a similar "My Computer" that lists current drives, and general PC info (in KDE, which is what we use in the office). Is there a way to list mounted drives in here, so that users can easily find the network drives? I'm open to alternatives to listing it in SuSE's sysinfo page, as long as it doesn't mean telling my old school windows users, "oh yeah, all your network drives are in /mnt/shares/...they wont have a CLUE what that means. It HAS to be easy for them to navigate to.
My attached image is just a screen shot of SuSE's "My Computer" so you can see where I would ideally like to put the shares.
Back in April I set up a Ubuntu DHCP server and a multiple VLAN network [URL] to migrate our various servers, workstations, etc off the 192.168.1.1 /24 network that everything was on because we where running out of address space. I built out the new network and everything worked great except our AD server would never get an IP address from the DHCP server (static reservation) and even if I set the IP statically on the AD server it couldn't ping the gateway and noone could log in. After several attempts to resolve this, including bringing in outside help, we where never able to figure out what the problem was.
Now 6 months later I have time to revisit the issue without effecting the live network. I used Acronis and imaged the AD server last Friday, cloned it on to another box with the same hardware, and put it up on the new network that's been sitting unused for the last 6 months. Today when I statically set the IP on the AD server (which is what I want) it connects and I can ping it's gateway 192.168.1.1 and all the way across vlans to a test sales agent workstation at 192.168.8.xxx on vlan 800 but only if I statically assign the agents station an IP address. When I try to get an IP address via DHCP it fails as destination unreachable. Nothing has changed in the last 6 months on the DHCP server but now it for some reason can't ping its default gateway 192.168.1.1. All of the config files are the same as they where left from the post linked above aside from the vlan id's used where changed from 1's to 100's (i.e. vlan 3 is now vlan 300) /etc/network/interfaces
Code:
auto lo
iface lo inet loopback
auto vlan100
iface vlan100 inet static
[code]....
why it can't reach the gateway, when I do a tcpdump I can see the DHCP requests come in on eth0 but the server never responds and I'm pretty sure its because it isn't "seeing" them since it thinks there isn't a network connection but I don't know how to trouble shoot to find out where the problem lies.

Ive seen this a hundred times while searching google but I can't seem to get any of the fixes suggested to work for me.
Here are the specs code...
I have other servers on the same network with the same software/hardware that never loses its mount to the windows share, and nightly backups are run through those mounts. So why does the mount on this machine fail when we do a push? The only conclusion that I can come to is there is some sort of time out on the windows server that causes this. The other servers that have this same type mount use their share every night, where as the share on this server gets used once or twice a week. Once the mount hangs I can not unmount it, I have to reboot the server. Once the server is rebooted the push works fine. But then the next week when a push is tried it hangs. What else can I check?
UPDATE: I've also tried NFS mounts and autofs mounts and they hang as well
I enabled logging by echo 1 > cifsFYI and this is what I see in var/log/message code...
Ive removed the actual file names for security concerns. Any one have ideas as to why this is happening? The only other thing I can think of to try is to swap out the NIC but it's at a remote location so I can't do that right now.
I have (had) a dual boot computer;Win XP and Ubuntu 10.10 64 bit.I decided it was necessary to enlarge my Root and Home Partitions. Using the instructions http://ubuntuforums.org/showthread.p...ome+Partitions I successfully enlarged the partitions and restored 10.10 (I used the copy command suggested by Irony). However when I boot the computer it boots to Ubuntu but no longer gives me the option of going into XP(it is not listed in Grub menu). Is there a fairly straightforward way of getting XP back on the Grub menu so I can boot to XP again?
View 5 Replies View RelatedI have been trying to get my Toshiba L300 to dual-boot Fedora 12 and Vista, which it came pre-installed with. I shrunk my existing partitions to create some unallocated space, then installed F12 on it from the 64bit Live CD. Everything seemed to go fine, and I was able to boot into Fedora as normal. However if I tried to boot into Vista, I would get a message to the effect of:BOOTMGR is missingRather annoyed but undeterred, I decided to cross that bridge when I came to it, and went back into Fedora to start configuring it properly. I installed the latest version of WINE, and the mp3 support, then shut down. When I tried to boot into Fedora later on, everything started as normal, then it hung on a black terminal style screen, where I can type and press return for a new line, but nothing actually happens. Pressing ctrl-alt-del restarts the computer however.
To get out of this no-working-OS-limbo, I had to break out my Vista recovery console and run fixboot. This has got rid of the bootloader and now Windows starts up fine, but obviously this does not solve the problem of not being able to boot Vista while Fedora is also installed, and not being able to run Fedora presumably (but not for certain) after I have installed WINE
I just reinstalled my windows partition from a backup image. Following that the Grub2 needed repair. That was accomplished and the grub2 menu along with the changes I made (to the grub screen) come up just fine. I can select my Windows 2K installation and it boots okay.when I select the "Linux 2.6.31-17-generic" the boot process appears to begin normally with the Ubuntu symbol shown, but at some point the screen goes blank and the boot process stalls. recovery mode gives me a jumbled up recovery menu. Alt-Ctrl-Delete gets me out of either.If I boot from the previous "Linux 2.6.31-14-generic", I�m receiving this error during boot-Quote:"One or more of the mounts listed in etc/fstab cannot be mounted"
There are subsequent screens that warn I'm running in "low graphics mode", but I can boot to a somewhat functional system. I was able to boot it once, but get the same results with either kernelThere is a difficult to read message in the jumble of the recovery menu.Quote:"One or more of the mounts listed in etc/fstab cannot be mounted.

Last week my server crashed. I'm trying to diagnose the cause.
This is the relevant error message in /var/log/messages:
Code:
I'm assuming that I can conclude, then, that apache/httpd was the cause of the memory leak?
Next, I've been tracking my memory usage. Using top, this is an average memory load level for my server:
Code:
I'd like to confirm if my understanding of this data is correct, because Plesk indicates that my memory usage is only 50% or less. (Though I have read a number of reports indicating that Plesk's measurements are frequently wrong.)
Top says: Of the 2,073,156K total memory, 1,982,572K (95.63%) is being used, 90,584K (4.37%) is free. Of that sum, 421,948K (20.35%) are being used as buffers. Additionally, of the 2,096,472K of Swap, 60K is used, and 887,700K (42.34%) is cached.
My questions: Is my memory actually being 95% used? Or is the buffered quantity (20.35%) not a use of physical/virtual memory? (i.e. is it disk usage?) Does the amount of cached Swap influence the percentage of physical/virtual memory being used?
In other words, who is correct? Plesk says I'm using 40-50% of my memory, whereas top says 85-95%.
Is it possible to like have SMS sent to your cellphone when the server crashes or a process on the server dies?
