A summary of the data recovery case for a VMware ESX server that took over a few days ago [Data recovery failure description] Sinopec Branch of a province, information management platform, several ESX server share an IBM DS4100 storage, about 40~50 group of virtual machines, occupy 1.8TB space, data is important. Normal work, VC reported virtual disk lost, SSH to ESX in the implementation of Fdisk-l view
Previously, all the company's VPS hosts often crashed and restarted, causing a great impact to the customer. The specific error message is a disk error. In view of the previous use of two 1 TB hard disks for RAID 1, now I want to add two 1 TB hard disks as RAID 1 and then add the new disk array to the original ESX system storage system. However, due to misoperations of IDC personnel, the disk is not added successfully, the original storage system cannot be recognized even after restoration. So I
On a storage area network (SAN), you can configure storage for virtual machines in two ways. One way is to use vmfs, which is a proprietary High-Performance cluster file system provided by VMWare Infrastructure (VI. For most enterprise applications, using Virtual Disks (vmdk files) on vmfs is the first choice. All available functions are supported in VI, includes Virtual Machine snapshots, vmotion, storage
ESX Server recommends using a VMFS file system for use as a virtual machine store, but VMFS is only a cluster class file system dedicated to VMware, so reading to the Vmfs file system can be a bit of a hassle. When you reinstall the ESX SERVER, or a VMFS STORAGE that is migrated from elsewhere, you need to reactivate
Tags: presence extraction using a contiguous VMFS storage space is data lossNow, with the advent of virtualization technology, many enterprises are starting to use virtualization technology. The principle of virtualization technology is to virtualize the hardware to different virtual machines. That is, a physical machine can have more than one virtual machine. However, if the physical machine fails or the storage server fails, the upper-level virtual
system can be connected to the storage, However, it was found that the ESXi system failed to recognize the original data store and Vmfs file system, and the administrator formatted the VMFS and found nothing inside."Data recovery process"The customer found several data recovery companies that took one weeks and still
This article is a case of data recovery for VMware virtual machines, although the entire VMware virtual machine data recovery process takes only three steps, but the problem analysis and experience summary are worth your reference.

Label:A Beijing real estate company, an HP Dl380g7 server, because of physical damage to multiple disks, resulting in raid crashes, data loss. The HP Dl380g7 server runs a Kingdee EAS system with a background of more than 40 GB of Oracle database, and the database data is very important. The HP Dl380g7 server is plugged into 8 146GB SAS disks, and each 4 disk has a set of RAID5, and a total of two sets of RAID5 are made into a RAID0, a total of 8 disk RAID50. 8 disk has 3 disk damage, and offlin

. Needless to be sure, the backup load is the maximum load that VMware servers assume. However, there are ways to solve these problems and, in some cases, to be more outstanding than the standard physical server backup and recovery methods. However, there are some misconceptions about these methods, as well as the implementation measures for Third-party backup/recovery products. In fact, many administrator
Category of Hard Disk faults Since the birth of computers, data recovery has gradually matured along with the development of computers. In today's information age, data recovery is even more important. Modern data recovery technology can solve data loss problems caused by multiple hard disk faults. To sum up, there are roughly three types of Hard Disk faults that
