I can mount it from the host using /usr/local/etc/vservers/unixdev1/fstab but have not figured out how to umount (if possible)
I was able to use the bcapabilities numeric values with out getting errors on vserver startup. cat /usr/local/etc/vservers/unixdev1/bcapabilities 0x00010000 0x00020000 0x00040000 even with this I am unable to unmount the nfs filesystem when mounted from the host into the vserver. when trying from inside the vserver I can not even mount the nfs filesystem sudo mount -v -t nfs calnfs01.corporate.net:/nfs_unix_data /unix_data mount: failed with nfs mount version 4, trying 3.. mount: permission denied the nfs server shows Oct 18 15:31:57 calnfs01 rpc.mountd: authenticated mount request from unixdev1.corporate.net:783 for /nfs_unix_data (/nfs_unix_data) Oct 18 15:31:57 calnfs01 rpc.mountd: authenticated mount request from unixdev1.corporate.net:787 for /nfs_unix_data (/nfs_unix_data) I have been working on this from several angles to no avail. Is anyone else mounting nfs into a vserver? How are you doing it? Are you able to umount it afterwards? thanks sig -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Magnuson, Sig Sent: Tuesday, October 18, 2005 11:50 AM To: vserver@list.linux-vserver.org Subject: RE: [Vserver] unmount nfs with vserver I have done the following but am getting a error sudo vi /usr/local/etc/vservers/caloratst01/bcapabilities VXC_SECURE_MOUNT VXC_SECURE_REMOUNT VXC_BINARY_MOUNT I also tried: SECURE_MOUNT SECURE_REMOUNT BINARY_MOUNT I am getting the following error on vserver startup sudo vserver caloratst01 start Unknown bcap 'VXC_SECURE_MOUNT' An error occured while executing the vserver startup sequence; when there are no other messages, it is very likely that the init-script (/sbin/init) failed. Common causes are: * /etc/rc.d/rc on Fedora Core 1 and RH9 fails always; the 'apt-rpm' build method knows how to deal with this, but on existing installations, appending 'true' to this file will help. Failed to start vserver 'caloratst01' Have I got the syntax of the file wrong? -----Original Message----- From: Herbert Poetzl [mailto:[EMAIL PROTECTED] Sent: Friday, October 14, 2005 11:18 AM To: Magnuson, Sig Cc: vserver@list.linux-vserver.org Subject: Re: [Vserver] unmount nfs with vserver On Fri, Oct 14, 2005 at 10:42:49AM -0600, [EMAIL PROTECTED] wrote: > A while back I posted to the list about mounting nfs filesystem into a > vserver.
