Re: how to replace a disk in a raid-1 array by a larger one?

Bonjour, I have a raid-1 array of 2 disks (1 Tb) and I want to replace these disks by 2 2Tb disks. Here is the result of lsblk for these disks: sde                         8:64   0 931,5G  0 disk ├─sde1                      8:65   0    40G  0 part │ └─md4                     9:4    0    40G  0 raid1 │   ├─systeme-swap        253:1    0     4G  0 lvm   [SWAP] │   ├─systeme-var         253:2    0    15G  0 lvm   /var │   └─systeme-chiffre     253:3    0    15G  0 lvm └─sde2                      8:66   0 891,5G  0 part   └─md5                     9:5    0 891,4G  0 raid1     └─data-home           253:5    0   891G  0 lvm   /home sdf                         8:80   0 931,5G  0 disk ├─sdf1                      8:81   0    40G  0 part │ └─md4                     9:4    0    40G  0 raid1 │   ├─systeme-swap        253:1    0     4G  0 lvm   [SWAP] │   ├─systeme-var         253:2    0    15G  0 lvm   /var │   └─systeme-chiffre     253:3    0    15G  0 lvm └─sdf2                      8:82   0 891,5G  0 part   └─md5                     9:5    0 891,4G  0 raid1     └─data-home           253:5    0   891G  0 lvm   /home My idea is to stop the array, remove one disk and have this array in degraded mode with the other disk. Then plug a new disk (2Tb) on which I build a new array in degraded mode with all partitions and lvm needed. Then I transfer all the data from the remaining 1Tb disk to the new array, replace the 1Tb disk by a new 2Tb disk and then synchronize the new array. Is it the good way to proceed? Or is there another better way? Thank you for all advices.
