Linux allows you to have one or more physical volumes on a single machine. Logical volumes can fit completely on physical volumes, even though you never unequivocally create them as adjacent. A logical volume could take part of all physical volumes. Sometimes, due to hardware failure, software malfunction and other reasons, one or more of your physical volumes may go bad and you have to replace them with new ones. In this process, if you do not have proper data backup, you will need disaster recovery skills to carry out Data Recovery. After adding new physical volume to volume group, when you reboot your system, Linux may put you in root maintenance shell if your logical volumes are not detectable by boot loader. When you use 'pvscan' to find out the volumes, you may get following error messages:"Missing UUID"and"PV unknown device"However, pvscan shows that all other physical volumes are intact. Only the replaced volume is unusable. Pvscan is a Linux command line utility t hat is used to scan all of the supported block devices in system for physical volumes. In this case, when you use fdisk, it shows that there is no partition table on the specified hard drive. In such situations, you can not boot your system and thus can not access the data stored on it. The whole behavior of your Linux system results into serious loss of critical data and put you in need of Linux Data Recovery. Linux Data Recovery is the process of retrieving lost, missing or inaccessible hard drive volumes and data from them. An absolute and quick Linux Recovery needs a powerful and highly developed Linux Recovery software such as Stellar Phoenix Linux Data Recovery. Phoenix Linux Recovery is an easy to use yet powerful application to ensure complete extraction of all your precious data. The read-only and non-destructive design of this robust Linux Data Recovery software performs precise Data Recovery Linux. It supports recovery from Ext2, Ext3 and ReiserFS file system ba sed Linux volumes.
