Huawei Exam H13-629 Topic 1 Question 14 Discussion

Actual exam question for Huawei's H13-629 exam

Question #: 14
Topic #: 1

Existing set customer of database uses a raw device, due to the large amount of data in the database. The customer plans to replace the old storage with new storage devices.

In the process of environmental inspection lvcb engineers found the following:

#getlvcb -TA sjklv

Intrapolicy =

copies = 0

interpolicy =

lvid =

lvname =

label =

machine id =

number Ips = 0

relocatable =

strict =

stripe width = 0

stripe size in exponent = 0

type =

upperbound = 0

fs =

time created = time modified =

As the vg is too large, the expansion of vg is impossible. As the service window is very short, and customers do not want to avoid the risk of large adjustments of the whole original environment, what is the recommended approach?

ABased on lvcb offset reconstruction nude equipment, and the database level 0 backup import

BUse the dd command for data migration

CUse the cplv command for data migration

DUse migratepv for data migration

Wow, this customer really likes to keep things interesting, don't they? I'd go with option D - migratepv seems like the most straightforward and reliable option here. Though I can't help but feel that the engineers need to do a bit more 'getting lvcb' and a bit less 'getting coffee.'

I agree, option D - migratepv seems like the best choice for data migration.

Hmm, this is a tricky situation. Since the VG is too large for expansion, I'd be hesitant to go with option B or C as they may not handle the data migration reliably. Option D using migratepv seems like the safest bet to me.

The lvcb information provided suggests there may be some underlying issues with the current storage setup. Using a raw device and the lack of copies and stripe width seems concerning. I think option A might be the best approach to safely migrate the data with a level 0 backup.
