Hi, i also want to manually clear a disk before removing it, but the disk is actually encrypted. From this list i want to clear the disk2: /dev/mapper/md1p1 on /mnt/disk1 type xfs (rw,noatime,nouuid,attr2,inode64,logbufs=8,logbsize=32k,noquota) /dev/mapper/md2p1 on /mnt/disk2 type xfs (rw,noatime,nouuid,attr2,inode64,logbufs=8,logbsize=32k,noquota) /dev/mapper/md3p1 on /mnt/disk3 type xfs (rw,noatime,nouuid,attr2,inode64,logbufs=8,logbsize=32k,noquota) /dev/mapper/md4p1 on /mnt/disk4 type xfs (rw,noatime,nouuid,attr2,inode64,logbufs=8,logbsize=32k,noquota) /dev/mapper/md5p1 on /mnt/disk5 type xfs (rw,noatime,nouuid,attr2,inode64,logbufs=8,logbsize=32k,noquota) /dev/mapper/md6p1 on /mnt/disk6 type xfs (rw,noatime,nouuid,attr2,inode64,logbufs=8,logbsize=32k,noquota) /dev/mapper/nvme1n1p1 on /mnt/cache type btrfs (rw,noatime,ssd,discard=async,space_cache=v2,subvolid=5,subvol=/) shfs on /mnt/user0 type fuse.shfs (rw,nosuid,nodev,noatime,user_id=0,group_id=0,default_permissions,allow_other) shfs on /mnt/user type fuse.shfs (rw,nosuid,nodev,noatime,user_id=0,group_id=0,default_permissions,allow_other) /dev/mapper/nvme1n1p1 on /var/lib/docker type btrfs (rw,noatime,ssd,discard=async,space_cache=v2,subvolid=5,subvol=/) /dev/mapper/nvme1n1p1 on /var/lib/docker/btrfs type btrfs (rw,noatime,ssd,discard=async,space_cache=v2,subvolid=5,subvol=/) /dev/mapper/nvme1n1p1 on /mnt/cache/system/docker/docker/btrfs type btrfs (rw,noatime,ssd,discard=async,space_cache=v2,subvolid=5,subvol=/) Is this the correct way to do it: 1. unmount disk2 2. execute this to use the decrypted/mapped device2 instead of the disk2 directly: dd bs=1M if=/dev/zero of=/dev/mapper/md2p1 status=progress

For me the same with v6.12.13 and many versions before... Hopefully this will be fixed soon... it´s a mess to use every time a "workaround" to get the GUI back working... :-( Oct 17 13:40:23 UnRAID nginx: 2024/10/17 13:40:23 [error] 30528#30528: nchan: Out of shared memory while allocating channel /temperature.

Hello, i have the exact same problem since some time. Additionally my server is slowed down (e.g. network performance) when this errors occur in the log: Apr 1 05:15:52 UnRAID shfs: fuse warning: munmap(0x14a136b6e000) failed Apr 1 05:15:53 UnRAID shfs: fuse warning: munmap(0x14a136b61000) failed Apr 1 05:15:53 UnRAID shfs: fuse warning: munmap(0x14a136b35000) failed Apr 1 05:15:55 UnRAID shfs: fuse warning: munmap(0x14a136b2c000) failed Apr 1 05:15:56 UnRAID shfs: fuse warning: munmap(0x14a136b22000) failed Apr 1 05:16:00 UnRAID shfs: fuse warning: munmap(0x14a136aef000) failed Apr 1 05:16:00 UnRAID shfs: fuse warning: munmap(0x14a0f2607000) failed Apr 1 05:17:11 UnRAID shfs: fuse warning: munmap(0x14a135de4000) failed Apr 1 05:17:12 UnRAID shfs: fuse warning: munmap(0x14a135df8000) failed What can i do to fix this issue? And NO, use only SMB shares is not an option on a linux system with several other systems in the network which must use the NFS share... Regards, sw4280 unraid-diagnostics-20230401-1310.zip
