LVM: Why do thin snapshots have the activation skip flag?
by berndbausch from LinuxQuestions.org on (#527QP)
LVM volume snapshots can be taken from thin volumes. By default, they have the activation skip flag set:
Code:# lvs
LV VG Attr LSize Pool Origin ...
thins1 vg01 Vwi---tz-k 1.00g thinpool thinvolumeI know that the flag can be reset with lvchange -a y -K.
My question: What's the rationale for setting this flag? Is there a risk when accidentally activating such snapshots?
