From be63ca6d037a954caacb3b9737332e886a1f762f Mon Sep 17 00:00:00 2001 From: Zac Dover Date: Sun, 19 May 2024 10:00:29 +1000 Subject: [PATCH] doc/cephfs: Squid and later - subvolume quiesce Add a note to the "Subvolume quiesce" section that says that the information in the section applies only to the Squid and later releases of Ceph. This is included here so that I don't overwrite the Reef and Quincy documentation with irrelevant information, and so that I don't overwrite the Squid information with blank space where the "Subvolume quiesce" section should be.
