Hi Neha,
We were repairing the cephfs metadata by using a alternate metadata pool
[1] and when running the "scan_inodes" stage I found that for some
objects listed in the data pool couldn't find the backtrace info. And
checked more and found that all the xattrs was erased from the head
object after the file was deleted.
Normally if there has no snapshot is created after the file being
created, when deleting the file all the related objects will be removed
from data pool. But before deleting the file if we create a snapshot the
related objects will be kept, but the xattrs will be erased, more detail
please see [2].
Is this a bug ? If not where could we found that xattrs ?
