A pardon, j'aurais dû indiquer que toute l'information (en anglais) se
trouvait dans le document que j'ai cité:

Reasons for mismatch_cnt

Neil Brown posted some comments on the mailing list: [4]. The md man page also states:

    On a truly clean RAID5 or RAID6 array, any mismatches should indicate a hardware problem at some level - software issues should never cause such a mismatch. However on RAID1 and RAID10 it is possible for software issues to cause a mismatch to be reported. This does not necessarily mean that the data on the array is corrupted. It could simply be that the system does not care what is stored on that part of the array - it is unused space. The most likely cause for an unexpected mismatch on RAID1 or RAID10 occurs if a swap partition or swap file is stored on the array.

Désolé, je supposais que tu savais l'anglais. En ce qui me concerne, je
navigue entre français, anglais, allemand et parfois italien ...
