Reply-To: LVM general discussion and development List-Id: LVM general discussion and development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , List-Id: Content-Type: text/plain; charset="us-ascii"; format="flowed" To: LVM general discussion and development With 2.6.21 kernel, when taking a snapshot of a volume with a XFS filesystem, does dm tell XFS to freeze the filesystem for the duration of taking a snapshot? Or should I use: - xfs_freeze -f ... - make LVM snapshot - xfs_freeze -u ... ? How is it made with recent kernels? -- Tomasz Chmielewski http://wpkg.org
