In the New config - Preserve current assignments, which one should I choose ? None All Parity disk Data slots Cache slots Thank, It is up to you - you just need to make sure that before starting the array the disks are assigned as you want them. in most cases it is easier to select the All option and make changes from that starting position.
January 3, 20215 yr Author Do I shut down my server, remove disk7 and replace the parity before doing the new configuration?
January 3, 20215 yr Author Or first, remove the disk7 from the array and make the new configuration ?
January 3, 20215 yr Community Expert Doesn't matter to New Config when or even whether you remove the disk. Just don't assign it when you New Config. Might be simpler for you if you don't remove it before doing New Config since it will be a missing/disabled/emulated disk until you rebuild parity without it.
January 3, 20215 yr Author I tried stop the Array. and the server keeps indicating "retry unmounting user share(s)" and the array don't stop !
January 3, 20215 yr Author I kill the process and is ok now. I have remove the disk7 from the array and change the parity drive. I make a new config, and tonight rebuild the parity drive. With your help, everything is under control... Thank,
January 4, 20215 yr Author Disk7 remove fro array : ✅ Parity disk remplaced : ✅ Parity disk rebuilded : ✅ Now, for the disk1 with errors, Is it better to add a new disc, copy the contents and redo a new configuration?by replacing disk1 with the new one? With this method, could I identify corrupt files? Or do I remove disk1, replace it with the new one, and let the system rebuild it? Thank,

January 4, 20215 yr Community Expert Yes, there were errors, so parity isn't 100% valid, best bet to recover the most amount of data and to be able to identity the corrupt files is to use ddrescue like I mentioned earlier.

What is the best command to run ? ddrescue --force... ?? Thank,
January 6, 20215 yr Author 😬 it seems complicated and an error can be fatal. In addition, the array is not accessible during this manipulation. How can I be on the hard drive numbers / identification? Edited January 6, 20215 yr by Jobine
January 6, 20215 yr Community Expert I find it pretty easy, but the other option it to just do a standard replacement of disk1, since you're using xfs there's no way of knowing which files will be corrupt though, unless you have pre-existing checksums.
February 7, 20215 yr Author Hi, I just added a new hard drive (sdh in unassigned) to copy disk 1. But, disk 1 no longer appears... is missing in the array. What is my best choice ? Thank,
February 7, 20215 yr Author After checking, I interchanged the SATA cables of the parity and of disk 1 ... this one was disconnected on the motherboard. Thank.
