PX6-300D storage pool

Hello,

 

I have px6-300D nas with 3TB X 6 drives. I configured it with Raid 5. Few Days back it was showing a message The amount of free space on your 'Shares' volume is below 5% of capacity.  and asked to overwrite Drive 6. So i ejected it after shutdown i  put it back and started.It get started rebuilding than. At 43% it got stuck and showing red indication, It was also messaging that your storage pool failed. in web access it was messaging your storage pool has failed and above message also. I tried restart and all but nothing has worked. Then after i contacted customer care they told that your few drives (3 or 4) has failed. they asked for dump file. as i wasold firmware the dump file was not getting generated. so i upgraded firmware as per instuction.  they conculed that your few  hard drive has been failed and go with some data recovery solution provide.  I really dont understand how would it corruprt my storage pool without any notice or mesage. If its NAS with raid protection my data must be protected. I really need my data back.

 

Till today i am receiving messaged like

The amount of free space on your 'Shares' volume is below 5% of capacity.

Data protection is being reconstructed on Storage Pool gstv. Reconstruction is 8% complete.

 

Reconstucting restarts at 45% starts with 0.

 

I wonder if reconstrcion is happeing how would my drives are failure.

 

Please help me ......

Re: PX6-300D storage pool

Hi I replied to your other posing as well but here is a link that may help explain disk failures.

http://en.wikipedia.org/wiki/Hard_disk_drive_failure

So were you able to get the dump file? Is tech support able to replace the failed drives or unit?

Raid 5 has a fault tolerance of one disk. You can only have one disk fail without loosing data. If you have multiple disk failures/errors then it will keep trying to rebuild but it will be unsuccessful. That is most likely why it gets stuck rebuilding. This is why we always recommend having a back up. If you do not have one you will need to take the drives to a data recovery service.

Re: PX6-300D storage pool

Thanks for your reply Westly,

 

I wondered about data capacity of Lenovo px6-300D. I observed that it was showing that "The amount of free space on your 'Shares' volume is below 5% of capacity".  After that it was getting hang few times. and fianlly raid got corrpted or HDD got faild. I have never faced any problem like this before In raid. I want to ask that Do i have a FIle systems can be storaged on another system so that I can recover if its get failed again. I mean I used to work with tyrone server with Fiber channel. It was getting mounted on windows system and shared thru SAN licences software. Is it possible that way? So i Can mount Lenovo EMC PX-6 300D volumes on a system and share it thru Windows PC. So that my file system and folder system would be safer. So that I will not have to go for costy data recovery service. Even I can try a free recovery softwares.

 

Please reply,

Re: PX6-300D storage pool

You can have the shares linked to your computer but is is not setup for SAN use. You want to keeps the files in 2 locations always or it is not a backup. Either keep it on your computer and the NAS or 2 NAS. Here is some info on what is a back up.
