+.TH BTRFS-CONVERT 8
|
||||
+.SH NAME
|
||||
+btrfs-convert \- convert ext2/ext3/ext4 filesystem image to btrfs in-place
|
||||
+.SH SYNOPSIS
|
||||
+.B btrfs-convert \fB[\-dinL]\fP \fB[\-r]\fP \fB[\-l\fP \fILABEL\fP\fB]\fP \fIdevice\fP
|
||||
+.SH DESCRIPTION
|
||||
+.B btrfs-convert
|
||||
+is used to convert a ext2/ext3/ext4 filesystem image to a btrfs one. This is
|
||||
+performed on an unmounted image. The conversion is done in-place and it's
|
||||
+possible to do a rollback to original fs. The original filesystem image is
|
||||
+accessible as a subvolume named \fIext2\_subvol\fP.
|
||||
+
|
||||
+The success of the operation depends on amount of free space in the original
|
||||
+filesystem, as btrfs uses this space to store it's own metadata and just adds
|
||||
+pointers to the data blocks.
|
||||
+
|
||||
+Duration of the operation depends on fragmentation and allocated space on the
|
||||
+orignal filesystem, it may take seveal hours for a terabyte-sized filesystem.
|
||||
+
|
||||
+If the operation does not finish succesfully, the image is recognized as the
|
||||
+original fileystem.
|
||||
+
|
||||
+.SH OPTIONS
|
||||
+.TP
|
||||
+\fB\-d\fP
|
||||
+Disable data checksumming. This may speed up the convert operation.
|
||||
+.TP
|
||||
+\fB\-i\fP
|
||||
+Do not convert ACLs.
|
||||
+.TP
|
||||
+\fB\-n\fP
|
||||
+Disable packing of small files.
|
||||
+.TP
|
||||
+\fB\-l\fR \fILABEL\fP
|
||||
+Set the label of btrfs filesystem to \fILABEL\fP.
|
||||
+.TP
|
||||
+\fB\-L\fP
|
||||
+Copy label from the original filesystem to btrfs.
|
||||
+.TP
|
||||
+\fB\-r\fP
|
||||
+Try rollback to the original filesystem. Beware that this may not always
|
||||
+succeed if the btrfs filesystem has been changed in a way that prevents this.
|
||||
+
|
||||
+.SH CAVEATS
|
||||
+The resulting filesystem will inherit the fragmentation and it's possible to
|
||||
+run whole filesystem defragmentation and then balance.
|
||||
+
|
||||
+The raid profile of both data and metada will be \fIsingle\fP, this is not the
|
||||
+same as default mkfs will create. Use balance with convert filter to change
|
||||
+raid profile you want.
|
||||
+
|
||||
+Security labels or quotas are not transferred to the new filesystem.
|
||||
+
|
||||
+Block sizes must be at least of btrfs supported size (currently 4KB on x86_64).
|
||||
+
|
||||
+.SH AVAILABILITY
|
||||
+.B btrfs-convert
|
||||
+is part of btrfs-progs.
