https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D230220 --- Comment #13 from Dexuan Cui <decui@microsoft.com> --- (In reply to Edward Tomasz Napierala from comment #12) kib is right. As I described in comment #9, the design of Hyper-V live back= up of a guest is that: the Hyper-V host only backs up the guest disk image, and the guest RAM is not backed up. The Hyper-V host needs to temporarily freeze the guest's mounted file systems to make sure they're consistent.=20 Thanks for the pointer to growfs(8). I'll study how it's implemented. @kib: I suppose you'll commit your patch soon: Created attachment 195685 [details] another fix, unsuspend on devfs_set_cdevpriv() error Thank you! --=20 You are receiving this mail because: You are the assignee for the bug.=
