Unclear to me still if this is a wipefs bug, or a btrfs fi show bug. That's the previous btrfs volume, which would have been a two disk, single partition only (on each disk), Btrfs volume, -d single -m raid1. I've got another case of this, and it's always multiple disk Btrfs volumes. btrfs subvol delete /tmp/btrfs-tmp.2ILsJ2v/rootġ0:33:26,593 INFO program: Delete subvolume '/tmp/btrfs-tmp.2ILsJ2v/root'ġ5:33:26,603 INFO program: Running. bin/mount -n -t btrfs -o defaults /dev/sda1 /tmp/btrfs-tmp.2ILsJ2vġ0:33:26,567 INFO program: Running. mkfs.btrfs -data=single -label=fedora /dev/sda1ġ0:33:26,101 INFO program: Running.

Version-Release number of selected component (if applicable): The solution is to restart the mon service the other is that there are few hard disks and many copies, and hard disks should be added at this time.A partition formatted btrfs, is wiped using wipefs -a, but btrfs fi show still sees the partition as a member of a btrfs volume. One is that a node is not turned on, or its mon process is hung up. Most of them are caused by two situations. #Modify permissions, send past sudo chmod 600 config Ssh-keygen # or ssh-keygen -t rsa #Modify file vi. #Set up the management node to allow passwordless SSH login, and switch all machines to the ceph-admin user #In the management node ![]() #Startup at boot sudo service ntpd restart # When the external time server is unavailable, use the local time as the time service Allow the upper time server to actively modify the local time Restrict 192.168.244.110 nomodify notrap noqueryĬomment out the 4 lines of server 0. iburst Sudo chmod 0440 /etc/sudoers.d/ceph-admin Sudo passwd ceph-admin #PASSWORD111 echo "ceph-admin ALL = (root) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/ceph-admin #Create ceph management user sudo useradd -d /home/ceph-admin -m ceph-admin Grep -color =auto '^SELINUX' /etc/selinux/config Sed -i 's/^SELINUXTYPE=.*/SELINUXTYPE=disabled/g' /etc/selinux/config Sed -i '/^SELINUX=.*/c SELINUX=disabled' /etc/selinux/config #download wget -O /etc//CentOS-Base.repo Installation documentation #Create a virtual machine, 3 hard disks per machine #Cluster planning, written in the /etc/hosts fileġ92.168.244.101 ceph1 #ceph-deploy,mgr,monġ92.168.244.103 ceph3 #mgr,mon #Change Ali yum and expl sources, executed on each machine cd /etc/ ![]()
