Hi cifs community, Problem: periodically (meaning that I don't know how to reproduce it) mounted windows share becomes inaccessible i.e. a simple ls -l command takes hours to output anything (normally it outputs the contents in the end though). Environment: MS Hyper-V with Server 2012 as a host facilitating communication between CentOS 6.4 and MS Server 2012 guests (everything 64-bit). On windows the folder was marked as public share. On CentOS cift-utils was installed and fstab entry looks as follows: //192.168.178.202/share /mnt/share cifs uid=504,username=myuser,dom=mydomain,password=mypassword,iocharset=utf8,noperm,ro 0 0 Note: Parallel to it there's also a network attached storage mounted with linux installed on it and has never failed me even with enabled suspend and hibernate modes. Also I can't find them now, but I've noticed some warnings in centOS logs saying that it failed to open a socket or something alike. Also I've asked this question before and found a workaround which doesn't help anymore. http://superuser.com/questions/678855/windows-share-is-not-accessible-from-time-to-time Question: since I'm not much of a network guy I can't find where the problem is located and am not even sure how to look for it so I would appreciate any advises on how to diagnose the problem and/or identify the source of error. Apart from that I'm wondering if this is a known issue and how one can resolve it. -- Cheers and best regards, Denys Sobchyshak -- To unsubscribe from this list: send the line "unsubscribe linux-cifs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
