However we\u0027re now unable to hard reboot boot-from-volume instances based on nfs volumes.\n\nNova-compute logs say the following after failing to hard reboot, with the error:\n```\n2026-05-12 16:24:07.137 7 ERROR nova.compute.manager [None req-9c592103-ce4c-45f9-b88b-754c39768ba0 ca5a98567fa64021a37883b38e1a4a90 30f77f4ca5504c81aaf294abf87a7b51 - - ac23823215e24239b1f693ed5a5ee2e6 ac23823215e24239b1f693ed5a5ee2e6] [instance: aa2a7be1-d015-4c74-aadd-dc7ed67a89b7] Cannot reboot instance: [Errno 16] Device or resource busy: OSError: [Errno 16] Device or resource busy\n```\n\nMounts in nova-compute container before \u0027Hard reboot\u0027:\n```\n(nova-compute)[root@c4bf1 /]# df -h\nFilesystem                                  Size  Used Avail Use% Mounted on\n10.154.75.77:/nfs_cinder012  3.0T  4.4G  3.0T   1% /var/lib/nova-mnt/68e9dc6dfb003d400795130e225adf40\n```\n\nMounts in nova-compute container after \u0027Hard reboot\u0027 and reset-state:\n```\n(nova-compute)[root@c4bf1 /]# df -h\nFilesystem                                  Size  Used Avail Use% Mounted on\n10.154.75.77:/nfs_cinder012  3.0T  4.4G  3.0T   1% /var/lib/nova/mnt/68e9dc6dfb003d400795130e225adf40\n```\n\nAs you can see it now changes back to nova/mnt after the error, where nova-mnt is to be expected.\n\n-----\nI\u0027ve tried two things to fix this:\n\n1 - Adding path /var/lib/nova-mnt to permissions of the config.json:\n```\n    \"permissions\": [\n        {\n            \"path\": \"/var/lib/nova-mnt\",\n            \"owner\": \"nova:nova\",\n            \"recurse\": true\n        }\n```\nThis unfortunately doesn\u0027t help.\n\n2 - Also changing the mount path of the host to nova-mnt (so both host and container using nova-mnt) like so:\n```\n  - \"{% if enable_shared_var_lib_nova_mnt | bool %}/var/lib/nova-mnt:/var/lib/nova-mnt:shared{% endif %}\"\n```\nThis resolved the problem, and should also still cover the mounting issue from the bug report (This change does require adding the path nova-mnt to permissions like in number 1.).\n\n-----\n\nI\u0027m afraid a change like this would have impact on upgrades for the operators using NFS for instances. Perhaps someone else can reproduce this bug and figure out a better solution to this problem.","commit_id":"004fdd42a83961e0364cc9906412a64f06cec02a"},{"author":{"_account_id":35263,"name":"Matt Crees","email":"mattc@stackhpc.com","username":"mattcrees"},"change_message_id":"2dc589629e45b06fdf342da53b7fbc830ed78b6e","unresolved":false,"context_lines":[],"source_content_type":"","patch_set":2,"id":"d20a4389_fda611eb","updated":"2026-02-17 17:29:11.000000000","message":"recheck","commit_id":"004fdd42a83961e0364cc9906412a64f06cec02a"},{"author":{"_account_id":35263,"name":"Matt Crees","email":"mattc@stackhpc.com","username":"mattcrees"},"change_message_id":"7b2f0d01237d7ec89fdee049036e0efc0b2c88db","unresolved":false,"context_lines":[],"source_content_type":"","patch_set":2,"id":"4bd1fbba_2e232fc1","updated":"2026-02-18 13:26:22.000000000","message":"recheck: POST_FAILURE","commit_id":"004fdd42a83961e0364cc9906412a64f06cec02a"},{"author":{"_account_id":37157,"name":"Robbert Nijgh","display_name":"Robbert Nijgh","email":"devops@rmnijgh.nl","username":"rmnijgh"},"change_message_id":"e7b613b2e5bef6b0f1a9178f51a5d3ab9bc56194","unresolved":true,"context_lines":[],"source_content_type":"","patch_set":2,"id":"3f35d8a0_7e71d100","in_reply_to":"542f805d_3af0a278","updated":"2026-05-12 15:01:16.000000000","message":"This also affects instances with a mounted nfs cinder volume, these also fail with hard reboot.
