gideva Posted August 9, 2019 Share Posted August 9, 2019 I had one disk failing so I decided to replace it with a new one... Followed the standard procedure but I got an error with the new one. I proceed with a read check and all good apparently. I tried again but no luck!!! Any Idea how to solve? Diagnostic attached monstruo-diagnostics-20190809-1925.zip Quote Link to comment
JorgeB Posted August 10, 2019 Share Posted August 10, 2019 Disk looks fine, replace/swap both cables/backplane slot with another disk and try again. Quote Link to comment
gideva Posted August 10, 2019 Author Share Posted August 10, 2019 I did as follow: - Stopped the array - Disconnected disk - Started Array - Stopped Again - Swapped disk to new slot - Started Array As soon as I start the array again the disk has a blue square next to it and the Data Rebuilt message is displayed on Array Operation section . but as soon as the array is active again the Disk is disabled (red x) and the following messages are displayed: Unraid Disk 1 SMART health [199]: 10-08-2019 11:33 Warning [MONSTRUO] - udma crc error count is 2 WDC_WD60EFAX-68SHWN0_WD-WX21D19A81X8 (sdo) Unraid array errors: 10-08-2019 11:33 Warning [MONSTRUO] - array has errors Array has 1 disk with read errors Quote Link to comment
JorgeB Posted August 10, 2019 Share Posted August 10, 2019 Do you have another disk to try? Quote Link to comment
itimpi Posted August 10, 2019 Share Posted August 10, 2019 Your steps look correct. Post the diagnostics following this operation. If the disk got disabled it means a write to it failed, and the diagnostics might give a clue as to why. have you tried any of the suggested action such as swapping cables or moving the drive? The fact you got a CRC error points to a connection problem and the cause of these can sometimes be hard to pin down. Quote Link to comment
gideva Posted August 10, 2019 Author Share Posted August 10, 2019 I will try with a different disk when back (in around 5 days). I did change slot and I also tried to put another disk in the supposedly failing slot. The replacement disk keep failing while the others works fine... Quote Link to comment
gideva Posted August 19, 2019 Author Share Posted August 19, 2019 Ok... New disk and I did it all over again. This time the process went through flawless but still all the data I had on the original disk are lost!!!! The reconstruction process went on for almost 18 hrs. but no files were saved at the end.... Any chance I can get them back from the original disk? Quote Link to comment

And by this do you mean that the disk is unmountable or empty? If umountable you need to check filesystem, if empty it means it was formatted by you during or after the rebuild. Quote Link to comment
gideva Posted August 19, 2019 Author Share Posted August 19, 2019 It has some data (448Gb) but the failing disk had almost 4TB. No formatting done (otherwise I guess the disk should be totally empty). I just finished and the entire process was ok... Quote Link to comment
gideva Posted August 19, 2019 Author Share Posted August 19, 2019 I am afraid that the data could be lost in the previous attempt (the disk failed after a while during the reconstruction) somehow (I must have done something). Quote Link to comment
trurl Posted August 19, 2019 Share Posted August 19, 2019 If the disk is mounting, and you can access its contents, then I don't see any way rebuilding could have made it lose only some of its files. Perhaps those 448GB are all new writes to an empty disk. How you got to an empty disk is unclear. Quote Link to comment
gideva Posted August 19, 2019 Author Share Posted August 19, 2019 What I did is the following: - Stopped the array - Disconnected disk - Started Array - Stopped Again - Swapped disk to new slot - Started Array The operation started with no problems and, after a while, out of the blue the reconstruction stopped. I tried to start it again but no joy. I tried wit a new disk and all went perfect (I thought) but the data are not there anymore... For sure I must have done something wrong but I did not probably realized I was f..ing up everything. Any way I can try to rebuilt the data from the failed disk (the very original one I mean)?

trurl Posted August 19, 2019 Share Posted August 19, 2019 If you still have the original disk and it can be read you can try to mount it as an Unassigned Device and copy the data from it. Quote Link to comment
gideva Posted August 20, 2019 Author Share Posted August 20, 2019 Ok... I have it and I was able to mount it as an Unassigned Device. It says that it has 3.48Tb used and 517Gb free. Now how shall I proceed? I tried with Krusader but I cannot see any file... Sorry for my questions but I am quite new at this Quote Link to comment
