I realise I am not alone in this, but I don't seem to be finding many solutions. I am running a CentOS box and * 1.09 with a TDM11B (1xFXS/1xFXO). Everything works great accept hang-up detection of incoming PSTN calls. * answers the call, but if the incoming caller hangs up, * does not release the line. I have determined the following information about my line: When On-Hook line voltage =

That is perfectly true. I had a beautiful bug in the code .... Switching from python to C have some weird side-effect. Indenting is not enough, brackets are required.... So I pushed https://github.com/ErwanAliasr1/syslinux/commit/5a122d218553a6d4019273653ba9fad66d6ae79e with the fix. I tested it on my multi-disk system with success. I also changed the name of the function. 2016-07-17 8:21

Hello, I did a virsh snapshot-create-as --domain meta sn1 --diskspec vda,file=/var/lib/libvirt/images/meta-sn1.qcow2 --disk-only --atomic --no-metadata Then I successfully blockcommitted 2 disks: virsh blockcommit meta vda --active --verbose --pivot virsh blockcommit meta vdb --active --verbose --pivot But when doing virsh blockcommit meta vdc --active --verbose --pivot I got: Block commit:

I''ve had a go at determining exactly what happens when you create a filesystem without enough devices to meet the requested replication strategy: # mkfs.btrfs -m raid1 -d raid1 /dev/vdb # mount /dev/vdb /mnt # btrfs fi df /mnt Data: total=8.00MB, used=0.00 System, DUP: total=8.00MB, used=4.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=153.56MB, used=24.00KB Metadata:

Hello people, I am having difficulties figuring out the POE power draw in watts from a Polycom IP601. I want to know how many IP601's can be powered from the Cisco Catalyst 3560G-48PS. The IP601 wallwart has: Input 120VAC 60hz 19W, Output 24VDC 500mA. I assume the output is appropriate value to figure out how many phones can be powered. The Cisco 3560 datasheet says "the 48-port PoE

Hello everyone, I'm unable to read temperature Gigabyte H77-DH3H motherboard. Is that motherboard supported or am I doing it incorrectly? When trying to access hw.acpi.thermal everything appears to be ok, but it is not, the system always returns 27,8C and 29,8C which fooled me initially - the values never change. Here is output: [chinatsu]:/root# sysctl hw.acpi.thermal

Thanks for you reply! Firstly, I'm very sorry I forgot introduce the scenarios in my experiments. Supposing a case, I have a virtual machine with two disks. One is mounted as a root partition and the other is data partition and the second disk is an iscsi lun, that is to say, not a local disk or image. Now the result wanted is that creating a snapshot for the root disk but not for the data

I have a CentOS-5.6 remote server in a house in Italy, where there are occasional thunder-storms. There was one yesterday, when the electricity went off 3 times, for a second or so on each occasion. My server, an HP MicroServer, came back (re-booted) on 2 of the 3 occasions, but not on the third. I assume that the problem arises because the machine does not close down properly. (Although it is

Hello, I''m testing Btrfs RAID1 feature on 3 disks of ~10GB. Last one is not exactly 10GB (would be too easy). About the test machine, it''s a kvm vm running an up-to-date archlinux with linux 3.7 and btrfs-progs 0.19.20121005. #uname -a Linux seblu-btrfs-1 3.7.0-1-ARCH #1 SMP PREEMPT Tue Dec 11 15:05:50 CET 2012 x86_64 GNU/Linux Filesystem was created with : # mkfs.btrfs -L

I've had an spa3k in service here at the house for a while now. After some initial wrangling, it's been working okay. I've had to reboot it a couple times and have noticed something rather annoying though. My setup is pretty simple and, dare I say, common. I have the SPA-3000 "inline" between my incoming POTS line and the internal house phone. It's setup to deliver

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, this is a new attempt to improve the output of the command "btrfs fi df". The previous attempt received a good reception. However there was no a general consensus about the wording. Moreover I still didn''t understand how btrfs was using the disks. A my first attempt was to develop a new command which shows how the disks

I've got a CentOS 5.6 guest running on 6.0 host. Using virsh attach-disk, I attached a new raw file as vdc However, the guest does not detect this new disk. In the past, I've used the following echo "0 0 0" > /sys/class/scsi_host/host#/scan command to make a CentOS system scan for new drives. However in the guest, there is no host in scsi_host so this isn't an option.

Firstly, it isn't necessary to hold lock of vblk->vq_lock when notifying hypervisor about queued I/O. Secondly, virtqueue_notify() will cause world switch and it may take long time on some hypervisors(such as, qemu-arm), so it isn't good to hold the lock and block other vCPUs. On arm64 quad core VM(qemu-kvm), the patch can increase I/O performance a lot with VIRTIO_RING_F_EVENT_IDX
