OpenSUSE Network :: 11.2M5 Mount T Cifs Terribly Slow
Aug 20, 2009
I used command as followings. nothing special. mount -t cifs //192.168.55.53/windows$/Home /mnt/ -o user=username%password It works well after mounted. But mounting itself takes 1-2 minutes terribly. After mounted successfully, file transfer speed looks to be normal.
1. 11.4 x64. 2. Solaris SMB server. 3. Gigabit LAN 4. mounted shares from that server (fstab entries)
write speed: 80-90-100 MB/s read speed extremely slow: 3-4-5 MB/s (really funny - our administrator shoked, but i'm not fun, i need fast lan for work)But when i reboot to windows 7 - i have 60-70-80 MB/s in both directions. Read and Write - nice.What happened? kernel updated and all last updates is applied (exclude kopete-because i use old kopete with animated tray icon).I have to tried many tunes like: "noatime" "directio" and also in /etc/modprobe.d - put conf file with: options cifs CIFSMaxBufSize=130048
We recently moved to a new home and I am trying to get my home file/print server set up again. Thanks to swerdna's excellent website, I got my server box (just upgraded from 11.0 to 11.2) running Samba and serving my shares over the network, and my "client" machines can access them without a problem.However, I'm not having much luck setting up CIFS mounts on my Linux desktop. I have my all-purpose user added to the Samba auth list (via smbpasswd), and configured my client as swerdna's howto's specify, and I can access the files just find. However, when I try to mount the shares with this command:
Code: mount -t cifs -o username=klein,password=klein //192.168.1.70/sharedmedia /home/zak/SharedMedia/ I get the following error:
Using Dolphin in Super-User mode, I can copy files and directories from the share to itself with no errors. Using Dolphin in Normal-user mode. I get the failure "Could not change permissions for...". The file is copied, but its owner,timestamp and permissions are wrong. If a subdirectory is involved, the copy aborts.
Using Windows XP I can copy files and directories from the share to itself with no errors.
Testing: If I mount with uid and gid, then my normal user can not access the share. mount.cifs //10.x.x.x/Data /home/stevej/Synology/Data/ --verbose -o user=stevej uid=stevej gid=users
Synology DS211 - There are 2 users on it. One of which is stevej and the other is julie. Rights RWX are applied to the users and the group called users. All files have stevej as the owner and users as the group with RWX Opensuse 11.4 - There are 2 pc's. One is run as stevej. The other pc runs as julie Windows 2000 - Runs as stevej and maps to the share as stevej.
Works as expected Windows XP - Runs as julie and maps the the share as julie. Works as expected Ultimately, I want the shares to automount at boot, or login and give the user full access. I have been to Swerdna's page and done as much as I can, but still no luck.
I'd like to have a CIFS drive mountable for various users. Each user uses different credentials and I want the drives to be automounted without using sudo-rights. I imagine the best thing to do would be to have the fstab entry point to multiple credentials files. Is there a way of doing that?
I've mounted a kind of proxy to map some cifs folders, 150 aprox. It umounts and mounts everything each hour, to check on changes on a configfile managed by a secretary, she just edits a file with names and I prepared a cron to notice the new mountpoints. It's a debian, no desktop , no nothing else. Just mount.cifs and apache2 to let the master webpage access to some files on each user samba home. The server has 4 cores and 2Gb of RAM. It's brand new, but it goes very slow.
Does anyone have an idea why is that working so slow? The apache is working well, it's the shell which is working extremelly slow.
Finally I updated my fedora 12 to 13 yesterday.I'm very pleased with some changes,even though it is not so obvious.However,I found that update my system through yum is such a hard work that I had to wait a long time because I got a terribly slow download speed.After some check,I found that I can't get access to ubuntu99.cn99.com and so on.Does anyone have suggestions what can I do now?
Just installed slackware-13, and sorting issues. I actually have googleearth running - just.It's telling me it's using opengl, but opengl is absolutely cat on this box I have ATI RS690M with the radeonhd driver on my laptop. Opengl is terribly slow. Videos stall, but I move them withmplayer -vo sdl <my_video>/end backgroundAnything I can do with Google earth?o option to swap. fglrx is crap on opengl.
today i decided i wanted to use the desktop cube again, so i went through all the compiz settings and got it working in gnome classic. however, when i initiate ratation with the mouse (ctrl>alt>button 1) it is sloooow whenever there is a window open (even just one). rotating away from the workspace with a window does seem to speed up the framerate. when i had maverick 10.10 it was never this slow.
So after having spent the past half year preparing to abandon Windows and come over to Debian I finally made the switch last night only to realize I forgot one important thing... I didn't figure out how to map the network drive on my Windows server (currently learning to replace this with Debian as well) to my Debian system.
I have read about 15 links but keep getting the following error: Mount Error (6): No such device or address
Here is what I'm trying to enter into my terminal (with important bits removed for security of course)
mount -t cifs //xxx.xxx.xxx.xxx/Network_Storage/ -o username=xxx,password=xxx /mnt/cifs
Q: How can I allow my users to mount a cifs share without an entry in fstab in OpenSuse 11.4?
I have an answer myself. Until OpenSuse 11.2 I could mount my samba shares by making mount.cifs and umount.cifs setuid root. Today I installed OpenSuse 11.4. Unfortunately mount.cifs isn't anymore allowed to be setuid due to security concerns. Security is not an issue in my case, so I copied the mount.cifs and umount.cifs from 11.2 to make it work again:
1. Download cifs-mount-3.4.2-188.8.131.52.x86_64.rpm from this repository (I use 64 bit): "http://download.opensuse.org/distribution/11.2/repo/oss/suse/x86_64/" 2. Extract the files mount.cifs and umount.cifs from the rpm and copy them to /sbin 3. Make them setuid root:
Code: linux-y5qw:~ # chmod u+s /sbin/mount.cifs linux-y5qw:~ # chmod u+s /sbin/umount.cifs 4. Mount your cifs shares as a normal user:
I mount the share on my Windows server with following command:
Code: mount -t cifs -o username=Administrator,password='mypassword',rw,dir_mode=0777,file_mode=0777,nobrl,uid=1000,gid=100 //10.8.0.1/users /mnt/
In my 11.3 computer it works well. I opening, copying files like I do in local filesystem. At the same time it's not working well on my 11.4 computer: the share mounts without errors, I see all files, can copy them from server to local computer. But when I'm trying to make copies to server, sometimes I receive messages like "Error writing file ...". Not always, but in the most part of my attempts. find the part of my /var/log/messages file:
Linux box info: root@mytestbox:~# uname -a Linux mytestbox 2.6.32-30-generic-pae #59-Ubuntu SMP Tue Mar 1 23:01:33 UTC 2011 i686 GNU/Linux
Windows box info: Windows Server 2008 SP2 Enterprise I've verified via --verbose output that mount.cifs is indeed processing the passed on options.
root@mytestbox:~# mount -t cifs //10.1.1.10/Test /root/testwin --verbose -o credentials=/root/testcreds,rw,nocase,noperm,noacl,nounix,noserverin o,iocharset=utf8,file_mode=0777,dir_mode=0777
Yet, when I type mount all it reports is (rw,mand). The share works just fine, and I can see the masking (all files are showing as rwxrwxrwx as expected etc) but mount is not listing the options?!
Is this normal expected behavior? Is there a bug report on this? I've google'd to the best of my capabilities and could not locate any such information which is why I decided to hit the forums prior to filing a bug.
I just made a fresh install of OpenSUSE 11.4-Tumbleweed and have the latest updates. However fstab lines I've used in the past are not working.
Here's an example of two: //IPADDRESS/share /home/user/mount cifs credentials=/home/user/.scripts/.creds,_netdev,uid=client_user,gid=users 0 0 //IPADDRESS/share /home/user/mount cifs guest,_netdev,uid=client_user,gid=users
I can execute a command
Code: sudo mount /home/user/mount and it works, but I'm wanting all my fstab lines to automount at boot as on other machines.
I have a SMB share being mounted during boot using a /etc/fstab entry.All that seems to work fine, but on shutdown or reboot I found that the system hangs for a variable period trying to unmount the share. It appears from the log that the unmount is happening after the network connections are closed.Is there someway around this, or is there some other way I should be mounting the share so that it is closes successfully at restart or shutdown?
I need to mount a windows share on my OpenSUSE 11.3. I get it using the mount.cifs command (by itself or using cifstab), but only root can rw file. I try the uid/gid parameters (also using forceuid) and the file_mode/dir_mode parameters, but I get the same behavior: all files and directory with rwxr-xr-x permissions and root/root (user/group). I read the whole section FILE AND DIRECTORY OWNERSHIP AND PERMISSIONS in man mount.cifs but nothing works.
Am in the process of upgrading from an ancient OpenSuSE release (7.2) to 11.2. One thing I have been unable to do that worked fine under 7.2 is remotely mounting a compact flash drive from an XP machine. Worked fine for many moons on 7.2:
# mount -t cifs -o rw //xpbox/'cf (H)' /cf0 I get: mount error(12): Cannot allocate memory Other cifs mounts of hard disks work fine.
I found a posting that says this means the memory allocation error is from the XP side. It says to fiddle with the XP registry, specifically IRPStackSize. I was not confident this fix would work since there should not be anything significantly more consuming with 11.2 compared to 7.2, and indeed, I got the same error after changing the parameter to 18 and rebooting the XP machine. Any ideas? I have some suspicion that the space and parenthesis in the share name might be fouling up someone. XP forces the share name to this for some reason.
I'm having some trouble in trying to make a clean solution and tougher time searching to not get the basic mounting pages/posts. So I thought I'd throw this out hereFor Oracle, we have an app server that runs /sharedapps and is an NFS mount for all other app/db nodes. What I'm working on now is that on this app server that hosts/exports /sharedapps file system has a sub folder with a CIFS mount (/sharedapps/data/appmount). e thing is that the remote nodes with the NFS mount to /sharedapps don't see the remote data in /sharedapps/data/appmount, only the main app server that has the CIFS connection. Realistically it makes sense why, but I'm trying to research if there is a way to have it do so. This is where I'm struggling. We are working on this in a dev instance right now but soon to be in production. In production, there are many DB nodes that could process a request which is why it would be best to have the NFS connection follow the remote CIFS connection
I have a Hitachi SimpleNET adapter (entry-level NAS device) on a Seagate FreeAgent 1TB external HDD (formatted ext3). The NAS device is connected over 100MB/s ethernet to a Netgear Wireless G router. All other devices connect using Wireless G. The NAS runs embedded Linux on an ARM processor and it runs vsftpd and Samba for file transfers.
If I transfer a large file using an FTP client the transfer maxes out at around 2.5MB/s. For my purposes that's good enough, especially considering the Wireless G bottleneck. If I transfer a file from a Windows 7 client (using samba) I get around 2.2MB/s. I know the CIFS protocol has more overhead than FTP and the difference in speed isn't that noticeable.Any combination of Ubuntu and Samba results in me getting less than 1MB/s. I've tried mounting it through Nautilus (GVFS) and /etc/fstab. FTP from this same Ubuntu client gets around 2.5MB/s.
I don't have root access on the SimpleNET to change the smb.conf. I've made a few adjustments to the mount options with no success. how to either speed up 10.04 as a Samba client or mount a folder on an FTP server locally? I've tried both curlftpfs and FUSEFTP. With curlftpfs any write operation results in an I/O error and it crashes intermittently. With FUSEFTP I never got that far and couldn't even browse the folder.
The shares get mounted correctly and you can navigate through the directories and open files.The only problem is that it randomly starts going really slow taking 30 seconds or longer to open a directory that has 2 or 3 files in it.I have tried quite a few things to try and fix this without any luck. Its getting to the point where I am having to consider recommending that we use windows instead, which I would rather not do as I think its good for students to experience different operating systems during school.
I've tried to get an opensuse box I have to share a directory via NFS. I've failed each time, but I thought that the third time, I'd enlist some help from the forums, if I could. how do I know that the nfs server and not the client is the problem? Short answer is: I don't! That's why nfs (and many netwrk problems) are laborious, you're troubleshooting needs to take place at both source and desitination. Next question, what do I have set up so far? Well, I did download the nfs server kernel stuff (two months back) and /etc/init.d/nfsserver start seems to get set up OK. No errors and the daemons nfsd, idmapd, mountd area all running. So, I *think* that part is OK. I have the share set up properly in /etc/exportfs and have "exportfs -r" it.
OK, now onto the trickier stuff: the client and iptables. On the client pinging to the nfserver box is perfect, and I have rpcbind running. the reported error is "mount.nfs: mount system call failed" though from experience nfs errors don't mean a whole lot.However, I will go off and check now and see if I need a mountd running on client-side too.Then there's iptables .... ouch, that could be a long and painful trek. I don't see any specific ports being blocked, and it's the iptables that the default v11.2 opensuse came with. I did turn them off and the problem was the same, so whether wishfl thinking or not, I'm hoping it's not an iptables issue.
I have one NAS device and using samba share one folder without password, how can I use command mount -t cifs to mount this share folder? I tried the below command, but always popup password checking?How should I do mount this folder without password checking?
I am trying to image about 30 laptops with WinXP, and I am using Clonezilla and DRBL for the task. We will start migration to Win7 starting Q4, so for now we are still using XP. I used a Clonezilla live USB to capture a standardized image to a CIFS/SAMBA share on the enterprise file server. The file server does not support NFS. To deploy the image, I used Virtualbox to build a VM with Centos 5.5 and then later Ubuntu 10.10. I mounted the CIFS share to /home/partimag but I found that I cannot share this CIFS mount out as NFS so I was unable to deploy the image with the image still residing on the CIFS; I had to copy the image to the VM's local drive.
Now using the DRBL live distribution, which is Debian based, I was able to obtain the image from a CIFS share and then share it out to the clients to be imaged as NFS (I think). I was able to use the DRBL live for some older computers, but since that hasn't been updated in nearly 2 years, I think it's missing some device drivers for my newer machines so it doesn't work on them -- this is why I looked at using CentOS and Ubuntu. To mount the CIFS shares, I'm using the following command:
mount -t cifs -o user@domain //share_ip_addr/share_name/folder /home/mount_point
Do I need to do something different to enable the mounted CIFS share to be shared out as a NFS share so that the clients to be imaged can see the contents from the CIFS share as a NFS share? The below image depicts my setup. The workstation has two NICs. The 10 network is the enterprise network and the 192 network is for DRBL imaging only. DRBL/Clonezilla does PXE boot and leases DHCP for the laptops. The laptops are shielded from the enterprise LAN; I am not doing any kind of NAT on on the server. The Linux VM is built with dual NICs and are set to bridged mode so they appear to be a separate NIC from the VM host on the network even though they going into the same port on the wall. [URL]
I'm trying to talk the studio I work at into switching one of the departments to linux. (likely kubuntu). So I'm trialling it, but having issues mounting windows shares.It's working great; all except that only Root can write to the mount. I've tried a few different things with fstab, no go.Below is my fstab so far, and you can see the mountpoints.
Code: # /etc/fstab: static file system information. #
This appears to mount correctly, however there are some filenames on the server with the bullet character() in their name, and by mounting via fstab, the bullet shows as a question mark, but mounting from nautilus shows the bullet.
Anyway I can mount with fstab, and have all characters show properly in the filename?
