Document URL: ################### https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.3/html-single/administration_guide/#chap-Managing_Snapshots Section Number and Name: ######################## 8.1. Prerequisites Describe the issue: ####################### There seems to be a mismatch in the specified chunksize for the given command and its description. In command, chunksize= 1280K, in its description : chunksize = 256KB Based on given command, the description should also mention chunksize=1280 KB. Detailed Description ##################### Navigation: ++++++++++++++++ Chapter 8. Managing Snapshots--> 8.1. Prerequisites--> Recommended Setup-->For Example--> 3. Create a thin-pool using the following Complete snippet from the doc +++++++++++++++++++++++++++++ Create a thin-pool using the following command: # lvcreate --size 1T --thin dummyvg/dummypool --chunksize 1280k --poolmetadatasize 16G --zero n A thin pool of size 1 TB is created, using a chunksize of 256 KB. Maximum pool metadata size of 16 G is used. Example Command section: +++++++++++++++++++++++++++ lvcreate --size 1T --thin dummyvg/dummypool --chunksize 1280k --poolmetadatasize 16G --zero n The chunksize mentioned in the example command is 1280k. But immediately below it, in explanation part, the chunsize is mentioned as 256 KB. Example description section ++++++++++++++++++++++++++ "A thin pool of size 1 TB is created, using a chunksize of 256 KB. Maximum pool metadata size of 16 G is used." ******************** Hence, in above line, we may have to change 256KB to 1280 KB as the mentioned example command is not using the default chunksize of 256KB. Suggestions for improvement: Additional information:
Ack for Doc Async Update 2.
In this case, I'd change the command to: --chunksize 256k Also the section above, i.e. Recommended Setup, should be updated to be consistent with content in the link "Chapter 21: Tuning for Performance".
