hi, the bio_check_ro function of the blk-core.c source file of the Linux kernel refers to LVM : https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/block/blk-core.c?h=v6.2.7#n500 how does LVM currently behave when faced with a device marked as readonly ? does it automatically switch itself in readonly mode? according to some tests carried out in a virtual machine, it seems that it doesn't and that LVM modifies the disk/partition(s) even though they are all readonly (chmod 444 && blockdev --setro). regards, lacsaP. _______________________________________________ linux-lvm mailing list [email protected] https://listman.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
