Hello to All, I’m using lvm2, I will create 2 striped LV which
volume group created by two PVs. When write happen, its will striped to two PVs
step by step. I know that when need to extend stirped LV, I have to add
two PVs more and extend the LV for do not get an error. Two question First; when I extend striped volume does it means I will
have 2 striped 2 linear volume group? Means chunk1 written to PV1 ,chunk2
written to PV2 and its over , it will pass second two PVs and chunk3 written to
PV3 ,chunk4 wirtten PV4 , right ? İf its right , when data is not big enough and chunk1 and
chunk2 enough to store, next write request time LVM start for first pair of PVs
or not ? Second; I would like to balance striped data when I add PVs to
extend related VG because first datas are written to only olds PVs and after
extend if read request happen still old disks will be used instead of this and
improve performance I would like to lay all data to all PVs after extend. İs there
any way to reallocation PEs ? Regards Vahric |
