bluestore_min_alloc_size_hdd = 4096

Description
Hi,
We’ve changed ‘bluestore_min_alloc_size_hdd’ to 4096 in ceph.conf and deployed disks with the new configuration.
The recovery has finished and we want to make sure the block size is indeed 4096 on the physical disks.
How can we do that?
We encountered a problem that we have some of the disks that are both old and new and we have no ability to identify them.
- Target version changed from v14.2.20 to v14.2.21
min_alloc_size is printed in hex at debug_bluestore level 10 when the superblock is opened:
int BlueStore::_open_super_meta()
{
...
dout(10) << __func__ << " min_alloc_size 0x" << std::hex << min_alloc_size
<< std::dec << dendl;
commit 4087f82aea674df4c7b485bf804f3a9c98ae3741 makes that more visible by logging at level 1, but that wasn't backported to nautilus or octopus.
- Status changed from New to Resolved
- Assignee set to Dan van der Ster
This have now been backported to the next nautilus/octopus release. #50549 #50550
- Target version changed from v14.2.21 to v14.2.22
