RE: help with ls command
I’m performing the ls command from an ssh sessions from another linux computer. The MTU was 1500 and I changed it to 1300 but the problem persists.

No the ls command is not in D state (if I’m not mistaking its state is S). Follow up question, then: Are you performing those operations over network? (and especially - over VPN/WAN/Tunnel)? If so, what you're describing sounds like the output packet sizes may be too large for your path's MTU. If you take the network interface you're coming through MTU and reduce it, to, let's say, 1300, does the problem persist?

help with ls command
I have 2 servers running Rhel5 and Centos5. Around 2 weeks ago on both of them , I have specific directories on which ls command gets stuck. I don't get any output from ls , I cannot stop the command - I only can close the window. I rebooted the servers and when I saw that reboot didn't help I ran manually fsck. No improvement. Has anyone any idea what can be the cause and what to do? Thank you ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Anything on dmesg when this happens? Did you verify that those directories are indeed on the volume you fsck'd ? (and not a network share, etc.) Are those 'stock' directories (part of the install) or something you've added? If stock, what's the path? (to know if it's a special one, augmenting the previous question) Is the problem with actual listing, or 'ls' itself? Did you try, for example, cat /path/to/dir/ tab tab to see if the shell does manage to read the directory contents? Do the stuck process get into D state (in 'ps axuf') like I assume it is? I know I didn't answer the question but maybe an answer to one of these questions might :) That's it for now... -- Shimi ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Please give a little more verbose output, so we can see the context of these
system calls.
By the way, nanosleep({64, 0}) means sleep for 64 seconds. What happens after
64 seconds?

bond on AS4 U6
I try to use bonding on AS4 U6 to connect to netapp ( it has also bonding) on nfs filesystems. When I reboot the computer without killing all the processes running on nfs filesystems , I get rpc error 101 cannot connect to netapp. The computer is stuck a couple of minutes and in the end reboots. Also when the computer starts up the first filesystem from the netapp is not mounted because bond is not up yet. How can we check is is wrong ? = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
