similar to: mounting none on /dev failed: no such file or directory

Hi all, do you know if there is a way at boot time do disable specific LUN's on a SCSI bus of a particular controller? I'm trying to write an udev rule, but it seems that the system ignores the "vendor" model/name of the controller... For example: I want to disable /dev/sdb; so I gather some information with udevinfo -a -p /sys/block/sdb and I try to use them to write

hi everyone I've been playing and trying to tell udev to ignore and not create symlinks in /dev but I fail. Hoping this is the one: ENV{ID_SERIAL}== I've tried: ENV{SYSTEMD_READY}:="0" OPTIONS+="last_rule" even ENV{UDISKS_IGNORE}="1" but udev tests would still show: ACTION=add and symlinks created. Would share an advice? many thanks, L.

Hello, someone used trixbox domU with xen? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello, I compiled xen on ubuntu, but at the bot i got the kernel panic message. I enabled the support to ext4 fs.

Hi, Looks like this patch broke automated builds due to a lack of a matching line in the defconfigs. Below is a patch that makes this a module for xen and xen0, unconfigured for xenU. That might not be the best thing here however. Thanks kurt Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> ===================================================== diff -r cd744c5ec950

Hola: Con esto del R me da la impresión que avanzo un paso y retrocedo dos! El caso es que tengo una "cascada de funciones", para realizar un análisis descriptivo "automático" en función del tipo de variable. Y en los resultados, en lugar de aparecer el nombre de la variable, aparece el nombre del argumento. Esto ocurre tanto si utilizo o no la función get(). Un ejemplo

Since we are using the m2p_override we do have struct pages corresponding to the user vma mmap''ed by gntdev. Removing the VM_PFNMAP flag makes get_user_pages work on that vma. An example test case would be using a Xen userspace block backend (QDISK) on a file on NFS using O_DIRECT. The patch should be backported back to 2.6.38. Signed-off-by: Stefano Stabellini

From: Jason Gunthorpe <jgg at mellanox.com> gntdev simply wants to monitor a specific VMA for any notifier events, this can be done straightforwardly using mmu_range_notifier_insert() over the VMA's VA range. The notifier should be attached until the original VMA is destroyed. It is unclear if any of this is even sane, but at least a lot of duplicate code is removed. Cc: Oleksandr

I have run out of ideas on why the local and remote back ups done with the script below behave differently. The local always seems to be a complete back up while the remotes are delta back ups except on Mondays. Cron line example: /root/bin/backups /export/home redwood "--exclude='*.sock' --exclude='*cache*' --exclude=/export/home/*/.gvfs" #!/bin/bash # Script for one

Since when we are using the m2p_override it is not true anymore that the mmap''ed area doesn''t have corresponsing struct pages. Removing the VM_PFNMAP flag makes get_user_pages work on the mmap''ed user vma. An example test case would be using a Xen userspace block backend (QDISK) on a file on NFS using O_DIRECT. The patch should be backported back to 2.6.38.

copy_to_user() returns the amount of data remaining to be copied. We want to return a negative error code here. The upper layers just call WARN_ON() if we return non-zero so this doesn't change the behavior. But returning -EFAULT is still cleaner.
