Hello people.
I need some help.
There is a customer using the command "dmsetup suspend" in order to
flush and suspend any I/O that has already been mapped by the device
but has not yet completed flushed during an snapshot execution with a HP
tool.
The question is: After execute the command "dmsetup resume" (to
un-suspends a device) the data integrity is guaranteed?
There is any problem related to the file system integrity?
The snapshot process takes about 10 seconds.
Any documentation is good too!
Thanks,
