Bug#754342: nfsroots: mount: Device or ressource busy
Package: base Severity: important When I boot my diskless client, I got a message on console: Begin: Running /scripts/nfs-premount ... done. mount: Device or ressource busy done. Begin: Retrying nfs mount This message is repeated about every second for about three minutes before the mount actually works and the services start. I got messages in the server (debian) syslog: Jul 9 08:36:03 Magnet rpc.mountd[31825]: authenticated mount request from 192.168.20.50:962 for /mnt/rootfs/stardust (/mnt/rootfs/stardust) │ Jul 9 08:36:03 Magnet rpc.mountd[31825]: authenticated unmount request from 192.168.20.50:962 for /mnt/rootfs/stardust (/mnt/rootfs/stardust) Here's the client's package version (debian jessie): linux-image-amd64: 3.14+57 linux-image-3.14-1-amd64 initramfs-tools: 0.115 Here's the server's package version (debian wheezy): linux-image-amd64: 3.2+46 linux-image-3.2.0-4-amd64 nfs-common: 1:1.2.6-4 nfs-kernel-server: 1:1.2.6-4 The problem I saw is that the rootfs is allready mounted and the initramfs tries to mount it another time, but fails about 200 times before stopping it and continue the boot.

Did you have wheezy clients with the same server which dont show this behaviour? cheers, Holger signature.asc Description: This is a digitally signed message part.
Bug#754342: nfsroots: mount: Device or ressource busy
I build my diskless client with the Ubuntu 14.04's debootstrap version. I made a basic bootable version and I added the desktop environment from that. For the export, I used this line. I used the same config for Ubuntu 13.04, 13.10 and 14.04 and I did not change this for debian : /mnt/rootfs/stardust 192.168.20.50(rw,async,no_subtree_check,no_root_squash) I'm not a nfs expert, but I think it's a nfsv3 configuration. I don't have any wheezy client, but I think the problem comes from the initramfs that tries to mount the rootfs a second time. For info, this is my boot command line for this host : kernel tftp://192.168.20.1//systems/stardust/vmlinuz ip=dhcp nfsroot=192.168.20.1:/mnt/rootfs/stardust root=/dev/nfs rw rootdelay=10 initrd tftp://192.168.20.1//systems/stardust/initrd.img I don't have a line in the client's fstab for the rootfs. -- Gilles Émilien MOREL cont...@gilles-morel.fr Le premier tirage aléatoire est [31, 19, 69, 10, 28] et le second est [9, 9, 9, 9, 9].
