Dotaz: SW RAID 1 - kontrola disků a opětnovné připojení

[Michnzee]

Dobrý den, potřeboval bych poradit ohledně softwarového raidu 1 na distibuci ubuntu skrze mdadm. Měl jsem v poli dva stejné disky (sda a sdb) ale obávám se že jeden umřel nebo se pole rozpojilo a momentálně je v degradovaném stavu. Viz:

root@server:~# mdadm -D /dev/md0
/dev/md0:
        Version : 1.2
  Creation Time : Wed Dec 12 22:38:19 2012
     Raid Level : raid1
     Array Size : 976598848 (931.36 GiB 1000.04 GB)
  Used Dev Size : 976598848 (931.36 GiB 1000.04 GB)
   Raid Devices : 2
  Total Devices : 1
    Persistence : Superblock is persistent

    Update Time : Wed Feb 26 12:31:48 2014
          State : clean, degraded
 Active Devices : 1
Working Devices : 1
 Failed Devices : 0
  Spare Devices : 0

           Name : server:0  (local to host server)
           UUID : 9bc23f7a:5c4b7602:77035a09:bc5f86ec
         Events : 1022720

    Number   Major   Minor   RaidDevice State
       0       8        2        0      active sync   /dev/sda2
       1       0        0        1      removed

Teď jsem trochu zmatený, jestli ten disk opravdu umřel nebo ne, protože když si vypíšu aktivní disky připojené v systému:

root@server:~# mdadm --query --examine /dev/sda
/dev/sda:
   MBR Magic : aa55
Partition[0] :        61440 sectors at         2048 (type 82)
Partition[1] :   1953460224 sectors at        63488 (type fd)
root@server:~# mdadm --query --examine /dev/sdb
/dev/sdb:
   MBR Magic : aa55
Partition[0] :        61440 sectors at         2048 (type 82)
Partition[1] :   1953460224 sectors at        63488 (type fd)

...tak se zdá že oba disky jsou v pořádku. Mohl bych se zeptat, jestli by mi někdo poradil nebo spíš vysvětlil co se stalo, popřípadě nenavedl jak vrátit oba disky do pole md0? Předem moc děkuji :)

Co vypíše cat /proc/mdstat?

[Michnzee]

Vypíše přesně toto:

root@server:~# cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md0 : active raid1 sda2[0]
      976598848 blocks super 1.2 [2/1] [U_]

unused devices: < none>

[Voty]

Z výpisů to vypadá, že sda2 je OK a sdb2 se odpojilo. Dobré je teď zjistit důvod, proč se tak stalo. Asi bych začal tím, že bych se podíval do logu SMARTu (pro jistotu do obou disků), jestli tam není nějaká hláška.

smartctl --all /dev/sda

smartctl --all /dev/sdb

[Michnzee]

Dobře, provedl jsem test obou disků viz:

Myslím, že oba dva disky vypadají v pořádku pokud se nepletu, žádné chybové hlášky v Error Log.

[Šangala]

Neprovedl jsi test, jen jsi vypsal údaje, test lze provést pomocí.

smartctl -t short /dev/sdb

nebo

smartctl -t long /dev/sdb

A ž test proběhne, vypíšeš si to znovu (průběh testu možná uvidíš ve výpisu, ale možná taky ne, nebo ti nepůjde výpis v průběhu testu udělat - je to dle daného disku).

[Michnzee]

Nejdřív bych to sdb2 zkusil zpět do pole přidat

mdadm /dev/md0 --add /dev/sdb2

V tom /proc/mdstat uvidíš, co to udělalo.

Máš aktuální /etc/mdadm/mdadm.conf a následně přegenerovaný initramfs, aby se do něj dostal ten aktuální mdadm.conf?

[Michnzee]

Tak jsem disk vrátil do pole a provedl opět výpis aktuálních informací, viz níže:

root@server:~# mdadm /dev/md0 --add /dev/sdb2
mdadm: added /dev/sdb2

- disk úspěšně přidán, nyní kontrola pole:

root@server:~# cat /proc/mdstat

Takže vypadá to, že se zadařilo. Ale absolutně nechápu proč se tomu tak stalo, že se jeden disk odpojil a vypadl z pole. Dalo by se to nějak zpětně zjistit? ještě že jsem si toho všiml, občas tu kontrolu udělám - proto mě to zarazilo že je v poli defacto jen jeden disk. V každém případě bych chtěl poděkovat všem zainteresovaným za pomoc.

[AraxoN]

Do mdadm.conf si daj svoju mailovú adresu a spusti mdadm démon /etc/init.d/mdadm - po výpadku disku z poľa Ti hneď príde mail.

Ako bolo povedané nižšie, SMART testy môžu tiež odhaliť chybu. To sa dá zase zadať do smartd.conf a spustiť smartd démon /etc/init.d/smartd

[Jendа]

Dalo by se to nějak zpětně zjistit?

Kernel nejspíš vypíše něco jako „media error“, „timeout“ nebo něco jiného. grepni syslog, messages a další (podle distribuce a nastavení rsyslogu) na název toho disku.

ještě že jsem si toho všiml, občas tu kontrolu udělám

Já dávám do cronu grep na "_" v /proc/mdstat s tím, že mi přijde e-mail, když tam je

[Michnzee]

Jinak jsem kontroloval v /etc/mdadm konfigurační soubor a přijde mi původní (s původními údaji) když jsem to pole vytvářel poprvé, někdy před rokem a něco...

[Michnzee]

puvodni jako neaktualni? aktualni udelas takto: mdadm --detail --scan >> /etc/mdadm.conf a pak v editoru vyhodis stary radky

ze smartu je videt, ze disky jsou ok, ale zatim jsi nikdy jest nepoustel ani jeden smart test, tedy treba jendou mesicne je dobre udelat smartctl -t long /dev/sda, kontrola vysledku pomoci smartctl -a /dev/sda

no a pole se muze kontrolovat treba jednou tydne pomoci echo check >> /sys/block/md0/md/sync_action, az to dobehne, tak kouknes do cat /sys/block/md?/md/mismatch_cnt a mely by tam byt nuly

nejlip si obe kontroly dej do cronu

[dustin]

Např. v debianu si ty checky pole hlídá balík mdadm sám (přidá si je do cronu).

Je potřeba nezapomenout na ten initramfs, aby bylo pole správně sestavené po restartu. Tipuji si, že restart se starým mdadm v initramfs byl důvod, proč tam to sdb není.

[Michnzee]

Ten původní konfigurační soubor byl vytvořený během instalace (když jsem nastavoval sw raid) a od té doby se na to nesáhlo, ale typy disků jsem nemělnil, takže po vygenerování mdadm --detail --scan >> /etc/mdadm.conf konfigu se UUID shodovaly s tím původně vytvořeným.

Když se všechna data opět sesypala dohromady tak jsem stroj ještě jednou přezkoušel, restartoval a všechno najelo v pořádku - takže skvělá práce a mnohé díky za pomoc. Pro kontrolu přidávám aktuální stav pole:

[Šangala]

Testnul si si i jestli ti ty e-maily chodí ?;)
Když by mi vypadl disk z pole, tak bych se nespokojil jen s opětovným přidáním a resync-em, ale aspoň bych si provedl test disků (+ prohledání logů).

[Michnzee]

Kontrolu jsem samozřejmě provedl, výpis pro první disk zde:

To už je lepší ;), pro fčul ten disk vypadá OK (tedy podle SMART).

[Michnzee]

Perfektní! :) díky za kontrolu

[lertimir]

Jak píše Šangala. Bez SMART testů bych si připojení neriskoval. Sám na většině disků provádím short testy v týdenních až 14 denních intervalech a long test v mesíčních až dvoumesíčních intervalech.

mismatch_cnt a mely by tam byt nuly

Pro zmatení nepřítele, pokud je na tom i swap (nebo možná i aktivně používaný soubor mapovaný do paměti) a bude se s ním aktivně pracovat v momentě check-u, tak tam ty nuly někdy/někde být nemusí.
