Hi all, I have an issue on my Ceph cluster. For one of my pools I have 107TiB STORED and 298TiB USED. This is strange, since I've configured erasure coding (6 data chunks, 3 coding chunks). So, in an ideal world this should result in approx. 160.5TiB USED. The question now is why this is the case... There are 473+M objects stored. Lot's of these files are pretty small. (Read 150kb files). Not all of them though. I am running Nautilus version 14.2.4. I suspect that the stripe size is related with this issue. This is still the default (4MB), but I am not sure. Before BlueFS it was easy to check the size of the chunks on the disk... With BlueFS this is another story. I have the following questions: 1. How can I check this to be sure that this is the case? I actually want to drill down starting from an object I've sent to the Ceph cluster thru the RGW. I would like to see where the chunks are stored and which size is allocated for these on the disks. 2. If it is related to the stripe size, can I safely adapt this parameter or is this going to work forward only, or will it also work reversely? Many thanks, Kristof _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
