Description
Technical field
The present invention relates to virtual machine technique field, it particularly relates to a kind of virtual machine on-line rapid estimation method, apparatus, set
Standby and storage medium.
Background technique
Usual user is to buy on demand for virtual machine, but with the increase of service application, incipient virtual machine
Configuration just can not meet the needs of user, this when, user will upgrade configuration and dilatation.
When some disk of virtual machine or inadequate volume space, the prior art can only be carried out by way of linux order line
" dilatation under line ":
Firstly, magnetic disk of virtual machine dilatation operation needs the state in view of host, the resource content for needing to check is complicated.
Host, that is, physical machine, disk dilatation function are the disk dilatations for virtual machine, and virtual machine is operated on host, every
Tens virtual machines are all run on host.When virtual machine carries out disk dilatation, widened disk size is fundamentally got on very well
From host, it is therefore desirable to first judge whether the disk space of host meets the size for needing dilatation.
Therefore, expand the corresponding logical volume of some mount point, when the space of logical volume is also insufficient, need to expand first
Physical volume.When physical volume is also unable to satisfy demand, need to increase newly one piece of disk from the host of virtual machine, and lattice are carried out to the disk
Formulaization operation, generates new physical volume, to increase logical volume, realizes the purpose of virtual machine dilatation." dilatation under line " refers to original
, existing, non-online disk dilatation operation is carried out by way of order line.
Secondly, give virtual machine dilatation manually by way of order line, need to log on to virtual machine, check disc information,
Expand physical machine disk size, expand magnetic disk of virtual machine etc., work repetition, low efficiency and easy error.Dilatation under existing line
Be to operator's operation behavior it is unwritten, be not easy that operation user and movement are recorded and inquired, cannot occur it is wrong
It mistakes timely positioning searching.
It needs first to log on to virtual machine in addition, carrying out online disk dilatation on platform, checks disc information, expand physics
Machine disk size expands a few step operations such as magnetic disk of virtual machine, meets necessary condition to check whether, for being unsatisfactory for these necessity
Condition, it can not all be operated by platform, it can only dilatation under line.Existing expansion method is more complicated, is unfavorable for user
It uses, influences user experience.

Breath judges the mount point with the presence or absence of individual disk, such as vdb, if so, expanding the space of the independent disk；
If it is not, i.e. under the mount point whole carry subregion, such as vdc1, vdd2, then judge whether dilatation size is less than institute
There is subregion residue disk space size, if it is not, executing step S102；If so, extension VG；
S102: detect whether all subregion residue disk space sizes are more than preset threshold (such as 50G), if so, explanation
VM disk space waste is serious, needs using operating under line, if it is not, then increasing disk newly.
Thus, it is possible to execute reasonable dilatation automatically according to the case where mount point, dilatation is avoided mistake or waste occur.
Fig. 3 is the flow chart that Linux type increases mount point newly.
Wherein, as shown in figure 3, the c. of Linux type increases mount point newly, comprising:
VGapp (one kind of volume group) is judged whether there is, if it does not exist, thens follow the steps S103；If it exists, then step is executed
Rapid S104；
S103: whether the configuration file for detecting LVM has volume list (volume list) limitation；
If increasing disk newly, and create VGapp and new LV without limitation；
If restricted, judge in limitation whether to include VGapp, if so, creation VGapp and new LV；If it is not, then using
It is operated under line；
S104: whether the configuration file for detecting LVM has volume list limitation；
If expanding VGapp without limitation and creating new LV；
If restricted, judge in limitation whether to include VGapp, if so, expanding VGapp and creating new LV；If it is not, then
Using being operated under line.
In addition, it is then disk size according to input that the c. of Windows type, which increases mount point newly, one piece of disk of mail, than
Such as vdc.
Thus, it is possible to which dilatation is avoided mistake occur.
Fig. 4 is the flow chart of the virtual machine on-line rapid estimation method of one embodiment of the present invention.
In order to guarantee that virtual machine reproduces going on smoothly for dilatation, before judging VME operating system type, further includes:
Whether group quota where detection virtual machine meets dilatation condition (that is, whether checking the current disk size of virtual machine
Meet size needed for dilatation)；And/or
Whether physical machine utilization rate where detection virtual machine meets dilatation condition (that is, physical machine where checking virtual machine
Whether class, if utilization rate alreadys exceed formulation standard, can be unable to dilatation with dilatation to utilization rate).
As shown in figure 4, firstly, detection detection virtual machine where group quota whether meet dilatation condition,
If so, detect whether physical machine utilization rate where virtual machine meets dilatation condition again,
If it is, VME operating system type is judged into above-mentioned step a.,
If the first kind, then step b or step c is carried out,
B. it pulls mount point size information and extends capacity；C. mount point is increased newly；
If Second Type, then step c is carried out,
C. mount point is increased newly.
Step b. pulls mount point size information and extends for example above-mentioned figure of specific steps that capacity and c. increase mount point newly
