EVA two disk failure in the same RSS

[noor Parkar_1]

HI,

The concept of RSS , disk group , Vdisk is clear.

but something i need to understand. Every one said , if two disk failed in the same RSS , there is data loss.

there is data loss only if following e.g 8 disk RSS group

another disk failure during reconstruction. then there is data loss.

not after disk reconstruction. am i right?

so after disk reconstruction, another disk may fail and there is no loss of data.

as i understand, after 1 disk failure, there is reconstruction within the same RSS first then disk levelling across all disk.

kindly clarify this point.

Yes, after a disk failure the EVA is reconstructing the data to get fully redundant again, until there is no free space left.

Problem is a second failing disk in the same RSS while the reconstruct is still in progress. This may render the complete diskgroup unusable.
