3.What /etc/exports entry would export a directory named /nfs to all clients on the subnet 192.168.10.0 and give them read-only access?
View 3 RepliesIs there an easy to make an entry in /etc/exports to export a directory for every entry in /etc/hosts?
View 2 Replies View RelatedOn a Lucid server, dnsmasq is happily running DHCP together with a local DNS; although, in setting up NFS, I seem to have a small problem... I have /etc/exports referencing the hostname of the clients but these IPs change when the DHCP lease is renewed. Unless I restart NFS or run exportfs, I cannot mount the exports on my clients. I know that it would be good to make the all the addresses static; however, I was wondering whether there is another way to configure NFS such as possibly adding in a script to continually monitor /var/lib/misc/dnsmasq.leases and re-export accordingly?

I need to create a directory named just like his parent.
Example:
I tried this but because there is "Space Characters" in the name of Parent directory, my script fails.
I have the following error on one of my servers. Is there a way to tell which directory is exactly having the problem? if there is, if i delete that directory, will that resolve the problem or no?kernel: EXT2-fs error (device md(9,0)): ext2_check_page: bad entry in directory #10158084: unaligned directory entry - offset=0, inode=605471640, rec_len=7606, name_len=177
View 4 Replies View RelatedWe recently upgraded our NFS server from Centos 4.4 kernel 2.6.9-42.0.10.plus.c4 to Centos 5.4 kernel 2.6.18-164.6.1.el5
In our queue directory where we shuffle files to be processes some files will go missing.
Example structure
/Queues/Process1/subdir_xxx
/Queues/Process1/subdir_xxx
etc...
/Queues/Process2/subdir_xxx
/Queues/Process1/subdir_xxx
etc...
Where 'xxx' is a date/time string down to the second.
Each subdir entry contains a number of files, depending on load at the time.
What we see happening is that a subdir will appear empty from a client (ls -la shows . and .. ) but an rmdir will fail with a 'directory not empty' error. From all 7 clients (mix of Centos 4 and 5). However on the server the files are visible. If we 'touch' the files the clients will then pick them up and process them.
It doesn't appear that waiting any amount of time will make the files visible (we've waited 8 hours while testing).
We've tried different mount options, NFS4, etc. Nothing got rid of the issue. Changing one server to use CIFS however solved it. So it appears to be some bug in NFS.
The problem appears to be intermittent and random, we can go hours without seeing it, or minutes. I'd say it affects fare less then 1% of the files written.
how do i remove it?

$ echo 2 * 3 > 5 is a valid inequality. This will create a file in the current directory named '5' with the number '2' in it, the names of all the files in the current directory, followed by the number '3' and 'is a valid inequality.'
What I do not understand is why 'is a valid inequality' gets written to this file. I thought it would write '2', all the file names in the current directory, then '3' into the file called '5'. Why does the 'is a valid inequality.' get written to the file also?
The *.dbf files (DBase III Plus files) have a header (metadata) and follow with n fixed records. I'd like to make a directory entry (like a symbolic link) that point to the fixed record area into a .dbf file. Is it possible in linux? The request is motivated by access a .dbf file from a Firebird SQL Database using CREATE TABLE EXTERNAL FILE '/tmp/mydbf.dbf' ( ... ); but this command only works on fixed records.

I'm running OpenSuSE 11.3 (64 bit) with the latest kernel update as of yesterday. I've recently moved from NFSv3 to NFSv4 on 4 servers. Between the 4 servers there are 9 exported directories. All of them work except 1 on 1 of the 4 servers.
/etc/exports
# NFSv4 fsid=0 for the top level directory
/export *(rw,fsid=0,async,no_subtree_check,insecure)
# End
# NFSv3
/export/apps/oracle *(rw,async,fsid=7,no_subtree_check,insecure)
/export/ftpserver *(rw,async,fsid=6,no_subtree_check,insecure)
# End
I had to keep the NFSv3 entry as I need that as the mount doesn't work with v4.

Well that explains why the NFSv4 mount of /apps/oracle fails because for some reason it can't "see" any files below that, but as I say the ftpserver sub-dir & mount are fine.
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 need to create and access a very large number of directories (and by large I mean millions). Each directory's name consists only of numbers, which are incremented every time a new directory is created (so there will be directory 1, 2, and so on).Of course I could just dump all these directories under the same parent directory, but I reckon I would run into filesystem limits. Moreover, I presume that entry lookup is not a O(1) operation, which means that lookup does not scale well.
One solution is to use some sort of prefix tree for storing the data. In this scheme, the data for directory "1234" would actually be stored in "/1/2/3/4".This solution has the advantage that each subtree never has more than 10 entries, but the disadvantage of requiring as many individual lookups as the length of the path.There are also intermediate solutions: using a maximum of 100 entries per directory, "1234" would become "/12/34", per example.In order to choose the best scheme, I must know more about the scalability of directory lookup under Linux. What's the maximum reasonable number of entries for a directory before lookup becomes too slow? Does someone know exactly what are the limitations of the algorithm used for directory lookup?

I'm trying to use Export Appliance utility to clone my virtual machines over local network using SMB protocol to NAS. I decided to do it because some machines are larger than free space on my local disk drive - lack of space for the clones. Simply, I specify GVFS path in the folder selection dialog box, for example:
/home/mloskot/.gvfs/mloskot on browarekhd/VirtualBox/clones
The process starts but after a minute or so the VirtualBox throws an error. Here is screenshot with the exact error:
Does it mean export over network is not supported? Does it mean there is a bug in VirtualBox? Or, simply I must not have used GVFS path as the one above as it consists of spaces in mloskot on browarekhd ?
UPDATE: Maciek suggested below to copy vmdk file to NAS manually. Generally, it would work, but as I specify in my question, I can't generate vmdk file (by exporting VM locally first) on my box where I keep all my VMs due to lack of disk space.

Exporting display from a Linux terminal to a Linux desktop is easy; you do the following:
On 192.168.90.121 (localPC):
xhost + 192.168.10.164
On 192.168.10.164 (remotePC):
export DISPLAY=192.168.90.121:0.0 <br/>
firefox
The Firefox window appears on my localPC. In the above case both PCs are Linux.
Can I similarly export the Linux display to a Windows PC? In the above example, localPC would be Windows and remotePC would be Linux.
