[pve-devel] [PATCH-SERIES manager 0/2] lvm config: check that --clear-needs-check-flag is set if there is a thin_check_options override

[Fiona Ebner]

Quoting the commit message from [0] verbatim:

> thin_check v1.0.x reveals data block ref count issue that is not being
> detected by previous versions, which blocks the pool from activation if
> there are any leaked blocks. To reduce potential user complaints on
> inactive pools after upgrading and also maintain backward compatibility
> between LVM and older thin_check, we decided to adopt the 'auto-repair'
> functionality in the --clear-needs-check-flag option, rather than
> passing --auto-repair from lvm.conf.

Unfortunately, there was already a user report without the override
[1], so this might not be the only issue. It's still worth warning
users about this though.

NOTE: For stable-8 the version check in d/postinst needs to be adapted
or maybe we want to run the check always there?
