No shame, new articles, new people. A lot of goods were lost at the Aunt. Including saw processors, dishwashers, and refrigerators, this is not a table today, mainly about storage hard disk replacement events. The old driver please tap. I bought it at a treasure. I bought it at JD. I bought it at JD. First introduce the home single device and topology. 1, NAS: You know! In addition to depositing SLR photos, the other you know. In order to protect the investment, did not buy 2-bay, directly on the 4-bay engage in RAID5. In addition, 88U of ASUS was added, and 802.3ad link aggregation was set up. 8 network ports, the first four LAN ports are each 1000Mb (the first two of which can engage in link aggregation), the latter four share a 1000Mb. 2. Router: Due to the UTP-CAT6 cabling of the entire house, all eight 1000Mb ports are now fully populated, so the value of the router that plans to buy four 1000Mb network ports still needs to consider redundancy. 3, other networking equipment: (1) Tianlong old power amplifier one, LAN5; (2) Samsung old TV one, LAN6; (3) millet box, LAN7; (4) Thunder download treasure, LAN8. See below: Hang your appetites first and open a box. The opening date is February. After 2 months of use, everything is normal. Under the Gigabit network topology, the read/write speed can reach about 100MB. However, the good times did not last long. I did not expect to hit me, ha ha. The Lord came, and on April 26, I opened the management interface and gave me a jump. . . I paid attention to this, but I still think he is because RAID5 can be linked to a hard disk, and the hard disk has another 2 years warranty. However, this situation that I have never seen makes me feel bad. Then opened: "Storage Manager" - "HDD / SSD" to see the following figure, shows that the hard disk 4 is in the "warning" state, the details show there are 402 bad sectors. But there is something weird here, and I haven't even wanted to understand now that there are many SMART states and IronWolf states. . . So Seagate hard drive manufacturers will not change the hard drive it? There is a hint of my heart. At the same time, the mobile phone mailbox also received a warning email sent by the NAS automatically, so I think it is necessary to make a mailbox prompt, as shown in the figure. Received the above email. At the same time, after searching, a solution was found on the Qunhui official website. It's very detailed. See the link below for details. With feelings of embarrassment, I think, straight out! How can it be? I didn't bother to back up the data, and if I couldn’t do it, wouldn’t it be okay if I couldn’t get back? Oh, it was too late. I was on the morning of the 27th. At the same time as unplugging, the buzzer recalled that the status light changed from green to amber. At this time, I turned on the computer and accessed the NAS. All kinds of visits had no effect. I also feel relieved, and I can use it without changing my service. The speed test was a bit slower than before and can be maintained at around 50MB/s. Unplug the hard drive and Zhang Ying, huh, huh, soon to see you disappear. After leaving the package and mailing, for the first time in a few days, nothing will happen. Hehe. Praise JD's customer service here. See below: Now it's gone by mail, and when it's time to mail it back, give everyone the steps to resume it. Summarize 2 points: 1, Qunhui RAID5 can be hot swap, rest assured. Finally, I hope that this low probability event will not happen to valued friends.
