similar to: how to find out total capacity and raid level of btrfs file system

Hi, I am working on system storage manager (ssm) trying to implement btrfs resize correctly, however I have some troubles with it. # mkfs.btrfs /dev/sda /dev/sdb # mount /dev/sda /mnt/test # btrfs filesystem show failed to open /dev/sr0: No medium found Label: none uuid: 8dce5578-a2bc-416e-96fd-16a2f4f770b7 Total devices 2 FS bytes used 28.00KB devid 2 size 50.00GB used 2.01GB path

Hello, I have a CentOS6 VM with davfs2 where I mount WebDAV Shares; one I have at a storage hoster and one I configured myself on a virtual server I rented on a hoster; why does 'df' always show the same value for capacity [root at centos6-vm ~]# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda3 11249272 7074512 3596664 67% / tmpfs

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:

We compiled xen-3.4.2 (2.6.18.8-xen). The grub entry, and the partition information to boot from /dev/sda1 is as follows. 1. /boot/grub/menu.lst: title Xen uuid 30ec981c-187e-4488-ae98-fe54ad13a77b kernel /boot/xen-3.4.gz console=vga module /boot/vmlinuz-2.6.18.8-xen root=UUID=30ec981c-187e-4488-ae98-fe54ad13a77b ro console=tty0 rootdelay=90 module

Hallo, linux-btrfs, I''ve (once again) tried "add" and "delete". First, with 3 devices (partitions): mkfs.btrfs -d raid0 -m raid1 /dev/sdk1 /dev/sdl1 /dev/sdm1 Mounted (to /mnt/btr), filled with about 100 GByte data. Then btrfs device add /dev/sdj1 /mnt/btr results in # show Label: none uuid: 6bd7d4df-e133-47d1-9b19-3c7565428770 Total devices 4 FS bytes

Chris: I can consistently reproduce I/O stalls when running fstress (as found in Autotest) against a six volume btrfs filesystem mounted without options. The volumes are independent disks from RAID controllers, and the test systems are eight core Intel and AMD machines running current btrfs-unstable. The stalls occur at variable times into the runs. The affected system ceases to do I/O

Hi Johnny, thank you for your and all centos team works. Many of us know how much work is needed for building new releases and maintaining C6 and C7, plus CentOS Stream and modules (Appstream). This is a huge work for a small team. Again thank you. For me OL is not an alternative. As reported in my previous message I'm not worried about how much time is required to build the new

I''ve just finished installing onto an OCZ Agilent v2 SSD with btrfs as filesystem. However to my surprise I''ve hit an ENOSPC condition one one of the partitions within less than a day of uptime, while the filesystem on that partition only reported 50% to be in use, which is far from the 75% limit people mention on the ML. Note that this occurs using a vanilla 2.6.32-rc5 kernel

Hi, I''ve been reading lots of documents and examples of setting up traffic shaping, and found that they _all_ refer to specific bandwidths for queues. I am using a dialup connection, and therefore can connect at different rates, and also have a dynamically changing ''bandwidth'' dependent on compression. What I want to do is to specify that interactive traffic (telnet,

Hi, I'm wondering what the proper way is to determine the utilization of host resources when running a couple of VMs. I know xentop but the man-page isn't exactly helpful in explaining what the values it displays actually mean. What I'm looking for is a way to say "Ok, i have 4 VM's running and right now they utilize 40% of the cpu resources the host has, 50% of disk i/o

Hi Bernd, There have been a lot of improvements in Samba since 2.0.5; I know that the 2.0.7 version is supposed to support unix HFS and VxFS quotas. Also the "with-quotas" option must be turned on at compile time, so perhaps your 2.0.5 version was not compiled "with-quotas"... I tested quotas and the HP 2.0.7 version here and it works the way that Dirk mentions, you will get

I create a volume?and mounted it, and use df command to view the volume Available and used . After some testing? I think the used information displayed by df is the sum of the capacities of the disks on which the brick is located. Not the sum of the used of the brick directory. ?I know the Available capacity, is the physical space of all disks if not quota? but used of space should not be sum of

Hi, is there a good reason why taskomatic check the number of real cores in the find_capable_host ?

I have a 1.8 GHz, 1 G RAM machine that I would like to use for conferencing. How many users have you all had on a box like that before? I have a Digium quad T1 card in the box right now, so I could have up to 96 users on this system. Has anyone ran into problems with degradation of service as the number of users increased. I haven't tested it out yet, but would be interested to hear any

Hi; I am in the process of planning a PBX/Voice mail system for a business with an ISDN phone system and somewhere on the order of 12 internal phones. The ISDN system appears to be a Primary Rate Interface, though this may be irrelevent because receptionists answer all inbound telephone calls before possibly transferring via the PBX, and most calls do not get transferred. Telephone use
