OmniOS - Wymiana dysków
Wymiana dysków w macierzy RAID-1
Czasem zachodzi konieczność wymiany dysków w pracującej macierzy RAID. Potrzeba taka pojawia się w dwóch przypadkach: jeden z dysków ulega uszkodzeniu lub trzeba wymienić dyski na dyski o większej pojemności. W obu przypadkach wykonujemy podobne, prezentowane poniżej, czynności.
Sprawdzamy status macierzy, którą będziemy modyfikować. W zależności od rozpatrywanego wariantu status będzie się różnił. Poniżej jeden z dysków został wcześniej wyłączony.

Procedura wymiany dysków możemy wykonać na wiele sposobów. Mamy możliwość zastosowania polecenia replace w przypadku posiadania dysku rezerwowego (spare part). W moim przypadku, korzystając z faktu posiadania prostego mirroru, zwyczajnie usuwam z macierzy jeden z dysków i zastępuję go nowym urządzeniem budując macierz od nowa.

W przypadku wymiany dysków na większe w macierzy systemowej, musimy ręcznie skonfigurować partycje. Wykonujemy to poleceniem format, wcześniej jednak sprawdzamy bieżącą tablicę partycji na obu dyskach:

W przypadku wymiany uszkodzonego dysku w tym miejscu procedura dobiegła końca. Jeżeli jednak naszym zadaniem było powiększenie dostępnej przestrzeni, to jesteśmy dopiero w połowie operacji.
Powiększenie macierzy
W tym miejscu opisanej procedury posiadamy macierz RAID-1 zbudowanej w oparciu o dwa dyski o różnych rozmiarach: 60GB i 80GB. Mamy możliwość łatwego rozszerzenia dostępnego miejsca poprzez wymianę dysku c0t1d0s0 na dysk o pojemności 80GB.
Pierwszym krokiem dalszej procedury będzie zmiana konfiguracji macierzy polegającej na włączeniu możliwości automatycznego rozszerzenia dostępnego obszaru zgodnie z konfiguracją sprzętową.
root@test-builder:~# zpool set autoexpand=on rpool
root@test-builder:~# _

Wymieniamy dysk.
root@test-builder:~# cfgadm -c configure sata2/1
root@test-builder:~# _
root@test-builder:~# _
Korzystając z faktu, iż oba dyski są identyczne, zamiast ręcznego konfigurowania tablicy partycji, możemy skopiować ich definicję z dysku systemowego:
root@test-builder:~# prtvtoc /dev/rdsk/c0t0d0s2 | fmthard -s - /dev/rdsk/c0t1d0s2
fmthard: New volume table of contents now in place.
root@test-builder:~# _

Następnie dodajemy dysk do macierzy i aktualizujemy MBR
