It's red again .....Well, the above data has explained the reason why RAID5 tend to hang two at a time--not the user RP problem, from the BER point of view, is the hard disk actually early bad bird, we did not find it. When a hard disk because of the MTBF cause the entire hanging off, the problem of the BER sector began to jump out of the stops me, so RAID5 is dead birds.We can

previous mechanical hard disk, easy to find files, in addition to a partition of the file corruption, does not affect other partition files.I want to ask everyone, SSD partition after ... such as a 240G solid-state drive, divided into 2 zones, a 100G, a 120G (the rest of the 20G for the moment) then, will 100G partition damage faster? Because I think, after the partition, the SSD in this section of the fil

remove it?Compaction is unavoidable, split can be automatically adjusted to manual.By turning this parameter value to a hard-to-reach value, such as 100G, you can indirectly disable automatic split (Regionserver does not split the region that does not reach 100G).With Regionsplitter This tool, split manually when split is required.Manual split is much higher in terms of flexibility and stability than autom

Partition Table reconstruction after corruption After installing Ubuntu at home on weekends, we encountered a tragedy of Partition Table damage. Fortunately, we finally found the lost disk data.Cause: The initial partition is windows, C: 40g, D: 100g, E: 100g, F: 250g. I plan to use g in drive F to install ubuntu, start the installation with the hard disk, delete the fdisk partition, and re-create each LI

harmful of these attacks. The principle is to send a large number of packets to the target server, occupying its bandwidth. For traffic attacks, simply adding a firewall is useless and must have enough bandwidth and firewalls to work together to protect against it. If you want to defend against a 10G traffic attack, you must use approximately 20G of hardware firewall plus nearly 20G of bandwidth resources. If the cost of a hard-to-prevent machine is quite high, the 10G hard defense will be tens
