Abstract
The invention discloses a method for monitoring the hard disk activity state of an LINUX server, and belongs to the technical field of computers. The method includes the following steps that firstly, a Shell script is arranged on the Linux server where hard disk activity needs to be monitored; secondly, parameters are input; thirdly, monitoring is started; fourthly, whether the Heartbeat.log is the newest or not is examined, wherein the current system time is regularly written into a USB flash drive, a heartbeat.log file in the USB flash drive can be stopped being updated if a system collapses, and the specific time period during which faults occur can be judged by examining the last record of the file; fifthly, test characters strings are regularly written into the hard disk in turns, if the situation is normal, the return value is 0 and no attention needs to be paid, and if abnormity occurs, mistake information is automatically collected and stored in an scanlog.txt file in the USB flash drive. The method has the advantages of being easy to operate, convenient to use and the like. No third-party software needs to be installed, and the method is simple and easy to use.
Description
Technical field
The present invention relates to field of computer technology, specifically a kind of method for supervising of LINUX server hard disc active state.
Background technology
Along with the development of server technology, the hard disk quantity that server is supported becomes more and more, and when meeting the growing data space of server, the work that also makes us monitor hard disk movable state becomes more and more loaded down with trivial details.Generally, if server has configured RAID card, while there is hard disk failure, may have chimes of doom, notify in time O&M personnel handling failure.But, if there is the problems such as SCSI hang or response timeout in RAID card itself, to directly affect system operation, and RAID card does not have any chimes of doom, now network also can lead to by ping, on surface, all are normal, only have O&M personnel discovery business to delay after machine and just can notice this problem, are difficult to the time that judgement is broken down.In addition, if server has configured SAS card, when hard disk occurs when read-write is abnormal also not have chimes of doom, so O&M personnel can only make regular check on the active state of each piece hard disk, guarantee that data access is normal.
Shell is a kind of programming language.As command language, its interactive mode is explained and is carried out the order of user's input or automatically explain and carry out pre-set a series of order; As programming language, it has defined various variablees and parameter, and many control structures that just have in higher level lanquage are provided, and comprises circulation and branch.
Summary of the invention
Technical assignment of the present invention is to provide a kind of method for supervising of LINUX server hard disc active state.
Technical assignment of the present invention is realized in the following manner, and method step is as follows:
1) to carrying out the Linux server disposition Shell script of hard disk movable monitoring, comprise altogether two program files of FSmon and Heartbeat;
2) input parameter: give script file and can carry out authority;
3) start monitoring: carry out shell script, monitoring server hard disk movable state;
4) check that whether Heartbeat.log is up-to-date: regularly in flash disk, write the current system time, if system is collapsed, heartbeat.log file in flash disk will stop upgrading, by checking the last item record of this document, and the concrete time period that just energy failure judgement occurs;
5) timing wheel flows on hard disk and writes test character string, if all are normal, rreturn value is 0, need not comprehend; Once occur extremely, automatically collecting error message and being dumped in the scanlog.txt file in flash disk.
Described FSmon is for the file system active state of all hard disks of monitoring server except system disk.
Described FSmon program implement: first check local disk, other dish quantity and identifying informations except system disk, extrapolation flash disk is mounted under system, each disk is carried out to data simultaneously and write test, when having hard disk or raid card abnormal failure, file system is read-only, but flash disk can also normally write, and program will write flash disk writing the information of reporting an error in time, and real time record goes out actual problematic hard disk position, thereby record when, and which piece hard disk failure causes the system failure.
Described Heartbeat is for the existing state of supervisory system dish.
Described Heartbeat program implement: in real time system disk is carried out to readwrite tests, if read-write success, return to right value in plug-in flash disk log recording file, when system disk fault, file cannot be read and write, return to improper value, in the time of in flash disk journal file, interocclusal record stops, thereby can know that system disk stops the time of response.
Compared to the prior art the method for supervising of a kind of LINUX server hard disc active state of the present invention, has the features such as simple to operate, easy to use, and this method, without third party software is installed, is simple and easy to use.Character string maker uses Shell script edit, and highly versatile, can cross-platformly be used.In addition, can custom scan interval, adapt to different monitoring environments.Support background monitoring, without human intervention simultaneously.

Accompanying drawing 1 is a kind of process flow diagram of method for supervising of LINUX server hard disc active state.
Embodiment
Embodiment 1:
Method step is as follows:
1) to carrying out the Linux server disposition Shell script of hard disk movable monitoring, comprise altogether two program files of FSmon and Heartbeat; Described FSmon is for the file system active state of all hard disks of monitoring server except system disk; FSmon program implement: first check local disk, other dish quantity and identifying informations except system disk, extrapolation flash disk is mounted under system, each disk is carried out to data simultaneously and write test, when having hard disk or raid card abnormal failure, file system is read-only, but flash disk can also normally write, and program will write flash disk writing the information of reporting an error in time, and real time record goes out actual problematic hard disk position, thereby record when, and which piece hard disk failure causes the system failure.
Described Heartbeat is for the existing state of supervisory system dish; Heartbeat program implement: in real time system disk is carried out to readwrite tests, if read-write success, return to right value in plug-in flash disk log recording file, when system disk fault, file cannot be read and write, return to improper value, in the time of in flash disk journal file, interocclusal record stops, thereby can know that system disk stops the time of response.
2) input parameter: give script file and can carry out authority;
3) start monitoring: carry out shell script, monitoring server hard disk movable state;
4) check that whether Heartbeat.log is up-to-date: regularly in flash disk, write the current system time, if system is collapsed, heartbeat.log file in flash disk will stop upgrading, by checking the last item record of this document, and the concrete time period that just energy failure judgement occurs;
5) timing wheel flows on hard disk and writes test character string, if all are normal, rreturn value is 0, need not comprehend; Once occur extremely, automatically collecting error message and being dumped in the scanlog.txt file in flash disk.
