Encrypted Volume and File System v2.0 Release Notes

1.7.4 vxresize -F Can Cause Data Loss or Corruption
The vxresize –F command resizes a VxVM volume and the file system mounted on the
volume. The vxresize command has no knowledge of EVFS, so if you configure EVFS on a
VxVM volume and then execute the vxresize –F command, vxresize does not allocate space
for the EVFS data structure (the EMD) on the volume. The vxresize -F command completes,
but file operations might fail; data might be lost or corrupted.
Symptoms
The vxresize -F command completes, but file operations might fail; data might be lost or
corrupted.
Workaround
Resize the VxVM volume and file system in separate operations. Use the vxassist command
to increase or decrease the VxVM volume size (or the vxresize command without the –F
option). Use the extendfs or fsadm command to resize the file system.
1.7.5 Renaming VxVM Volumes with EVFS Enabled Makes the Volume Unusable
The vxedit rename command renames a VxVM volume. The vxedit rename command has
no knowledge of EVFS, so if you have a VxVM volume with EVFS enabled and then rename the
volume, the mapping between the VxVM volume becomes unusable. EVFS commands fail.
Symptoms
The vxedit rename command will complete, but subsequent EVFS operations fail.
Workaround
Disable EVFS and unmap the EVFS volume before renaming the underlying VxVM volume.
After you rename the VxVM volume, you must map the new VxVM volume name to EVFS and
enable the new EVFS volume.
