Hello!
When trying to do a pvmove on a mirrored logical volume
I get the message "No data to move..."
pvmove /dev/dasdx1
Skipping mirror LV m1m
Skipping mirror LV m1m_mlog
Skipping mirror image LV m1m_mimage_0
Skipping mirror image LV m1m_mimage_1
No data to move for main
Looking in the pvmove code reveals that mirror lvs are
intentionally skipped:
--snip--
if (lv->status & MIRRORED) {
log_print("Skipping mirror LV %s", lv->name);
continue;
}
if (lv->status & MIRROR_LOG) {
log_print("Skipping mirror log LV %s", lv->name);
continue;
}
if (lv->status & MIRROR_IMAGE) {
log_print("Skipping mirror image LV %s", lv->name);
continue;
}
--snip--
What is the reason for this?
Best,
Jens
