One of my first encounters with the Beautiful BSD Operating Systems was on a machine that Loves Pepper.

It was configured to do one task and do that one task well. The machine was a file server configured to serve diverse clients with speed agility and redundancy. The machine which loved to be called ChiliBox had space for just a couple of hard drives HDDs. That meant that if you want it true redundancy, you had to connect external hard drives
Those enclosures could also be provided by the hardware vendor

The ChiliBox was a fun toy to play with

It served my clients well for a number of years where all that was needed was to swap out hard drives which were worn without losing any data the only patience the client needed to have, is to make the resilvering of the new HDD complete itself.

Khi dùng NAS (RAID5) cho DB SQL trong Docker/Portainer Swarm, dữ liệu dễ bị lỗi & trễ phản hồi. Lệnh mới: bỏ Swarm, tìm giải pháp lưu trữ SQL an toàn, đảm bảo sao lưu và phục hồi nhanh. Cần mẹo từ DevOps?

Tôi đang cố khôi phục dữ liệu NAS QNAP TS‑431P2 sau khi mất quyền admin. RAID5 vẫn sạch, nhưng LVM thin‑pool không thể kích hoạt trên Linux do “Unrecognised segment type tier‑thin‑pool”. Đã thử Ubuntu 18/20, Mint, SystemRescue nhưng vẫn lỗi. Cần ảnh VM QTS 4.3.x để chạy môi trường khôi phục. #QNAP #NAS #RAID5 #DataRecovery #Selfhosted #khôi_phục_dữ_liệu

What is Erasure Coding – A Shield Against Data Loss

Erasure Coding (erasure code) is a data protection mechanism that protects against data loss by breaking data items, such as files, into fragments, calculating additional data pieces (parity information), and storing them across a set of independent locations or storage media. For decades, traditional methods like replication have been the go-to solution for protecting against data loss or corruption. In recent years, however, a more efficient and resource-friendly technique has become more […]

@madeindex I did have a #fedora box but over a year and a half ago I made a terrible mistake at stupid o'clock. One disk had a SMART error (bad sector) so I replaced it .. but then I thought to self: why not make /boot #raid5 like the others (server is #raid6 and #raid1)? I was not thinking ... /boot was messed up. Couldn't salvage it. And I haven't been bothered enough to repair it. #anaconda is pathetic with md+lvm and I have the laptop so not worth it to me for now.
Synology 群暉 DS918+ RAID5 專業資料救援成功案例
客戶設備:Synology 群暉 DS918+ 四 Bay NAS
硬碟配置:Seagate 4TB IronWolf NAS 硬碟 x 4 顆組成 RAID5
檔案系統:btrfs
故障原因:HDD 1 出現壞軌,客戶誤操作導致 RAID 陣列損毀

故障經過
客戶因為 NAS 出現警報,DSM 系統顯示 HDD 1 硬碟出現壞軌警告。客戶擔心資料安全,將 HDD 1 取出嘗試使用 Windows 系統進行修復。

不幸的是,在處理過程中客戶不小心將 HDD 1 與 HDD 4 混淆,並對其中一顆硬碟執行了 diskpart 清除動作,導致重要的 RAID 資訊被破壞。

當硬碟重新接回 Synology DS918+ 後,NAS 系統無法正常識別 RAID5 陣列,所有重要資料都無法存取。

I had to decide -- more burn-in to check for early errors or just build the array and let it detect them? So I fired up mdadm to create my #RAID5 array and that took literally all day. Oh and today too. But its done now and I downloaded 15 GiB from one and 17 GiB from the other event off my main camera.
I can finally fire up #darktable and start culling and processing pictures.
Dear fellow photo #geeks, its not just you. It happens to all of us.
Also please be patient, I'll post #photos soon!
Random update that hits both my #photog and #sysadmin roles; I ran out of disk space for my raw #photography recently. I have a home-made #NAS box with a pair of disks in #RAID1 running Rocky Linux and I needed to get more space. I spent an evening shopping around for the best value I could get in local disks and that required driving to three Canada Computers locations to pick up one drive at each so I could build a #RAID5 array and not deal with this again in the near future.
