That's definitely good advice, but even with e2fsprogs 1.35, if e2fsck -f is

Commit 4490001029012539937ff02778fe6180613fa949 ("virtio-net: enable multiqueue by default") blindly set the affinity instead of queues during probe which can cause a mismatch of #queues between guest and host. This patch fixes it by setting queues. Reported-by: Theodore Ts'o <tytso at mit.edu> Tested-by: Theodore Ts'o <tytso at mit.edu> Cc: Neil Horman <nhorman

hello, i just wanted to know how to move files from the master node to slave nodes...for example i have 10 files in the master and i want to move 2 files to each slave node...how do i do that....i have redhat7.2......i tried rpc but it said command not found...i am using a beowulf cluster. your's sincerely, devi vijay Get Your Private, Free E-mail from Indiatimes at

virtio-blk set the default queue depth to 64 requests, which was insufficient for high-IOPS devices. Instead set the blk-queue depth to the device's virtqueue depth divided by two (each I/O requires at least two VQ entries).

But if the goal is to provide something like getrandom(2) direct from the Host OS, it's not necessarily harmful to allow the Guest ring 3 code to be able to fetch randomness in that way.

I think this is really an attempt at user feedback, rather than user discussion. But there's no such thing as a user-feedback mail list. Nevertheless, others may find this pertinent: why doesn't mke2fs handle USB's competently? And if it does, why doesn't it reassure me so? And how can I handle a linux-formatted USB flash drive in the absence of my system giving me any guidance?

I've backported all of the bugfixes to the 2.5 dxdir/htree patches to 2.4, and have created a new set of patches for Linux 2.4.21rc5. At this point it *looks* like we've fixed all of the htree bugs that people have reported, including the brelse bug, the memory leak bugs, and the NFS compatibility problems. I've done *very* light testing, and things seem to work, but I'm now

I'm trying to clone a volume in a storage pool and I'm following the steps described here: http://libvirt.org/docs/libvirt-appdev-guide-python/en-US/html/libvirt_application_development_guide_using_python-Storage_Pools-Cloning.html My code looks like: destXML = """ <volume>
