 Posted: Sun Aug 07, 2011 10:13 am Post subject: [SOLVED] mdadm raid1 sync resync e desync... |
 |
|
ciao a tutti,
ho un problema con il serverino che ho creato per un ufficio...
Dato che il proprietario ha le braccine corte non ha voluto comprare un bella scheda raid hardware, ma mi ha imposto di creare un fakeraid con mdadm...
L'array è composto da due semplici WD caviar green da 500GB l'uno.
L'array è stato creato correttamente ed era perfettamente funzionante. Durante il trasporto si è leggermente smollato il cavo sata di un hd e, di conseguenza, alla successiva accensione l'array si è degradato.
Me ne sono accorto solo dopo alcune ore ed ho quindi dovuto risincronizzare i dischi.
E' andato tutto perfettamente: la sincronizzazione è avvenuta in poche ore ad una velocità di 40-50MB/sec.
Dopo circa un mesetto mi arriva una mail informandomi che una partizione del disco è andata fuori sincronia. Provo a risincronizzarla e procede tutto normalmente.
Dopo un altro mesetto arriva un'altra mail che mi informa che ben due partizioni si sono desincronizzate ( si vedeva anche prima del desync dato che lavorandoci sopra alcuni file davano errori di copia, era tutto lento, ecc... ).
Ho deciso subito di mandare in fault tutto il disco a cui appartenevano le partizioni desincronizzate e di ordinare subito un disco uguale a quelli presenti nell'array.
Dopo pochi giorni mi armo di buona volontà, prendo il disco nuovo e procedo alla sostituzione.
Sostituisco il disco, accendo, parte gentoo e procedo alla risincronizzazione e bam...
Non si schioda dai 2-3MB/sec ed adesso è arrivato ad andare a 300 KB/sec... mi ci vogliono due settimane a questo ritmo...
Non so da cosa possa dipendere. Il disco sostituito era quello guasto ( secondo mdadm... ) ma gli sto dando una ripassata con badblock e non trova nulla di strano... che mdadm abbia abagliato ed io abbia tolto quello non guasto?
Adesso devo andare, stasera vi posto più informazioni!
Grazie in anticipo!

Non è detto che hardware sia meglio (con linux, non con altri OS).
Personalmente, dato il costo dei dischi preferisco avere un disco di sistema non raid e mettere in raid 0 e 1 le aree che mi interessano.

Mi pare di intuire che sei su un sistema low-cost, un minimo di informazioni in più non guasterebbero, ma ho avuto diversi problemi di connessione dati ed alimentazione con le unità sata. Dipendeva dalla pessima qualità dei connettori della MB e della PSU.
Non è che nei log del sistema hai qualche errore di comunicazione ricorrente con i device?
Bada che la geometria di default di fdisk dovrebbe essere cambiata (nuovo default -c=nondos -u=sectors da meno di un anno) e quindi potresti avere qualche problema (partizione raid leggermente più piccola? di 1536 giusti giusti? un fdisk -l non guasta).

possibile, ma tieni anche conto che i nuovi WD hanno qualche problemino di compatibilità (ora non ricordo cosa ma era un problema di geometria). Sicuro che sia esattamente lo stesso?

Mi puzza davvero molto che i dischi ( sia quello vecchio che quello sostituito ) abbiano identificatore 0x00000000.

Ora sta andando peggio: il sync procede a 46-60 KB/sec e tutto il sistema procede a rilento in quanto la cpu ( AMD Athlon II X2 245e 2.9Ghz 2x1MB AM2+/AM3 Regor 45W BOX ) è perennemante in waiting state.
Inoltre qualsiasi operazione che riguarda il nuovo disco ( /dev/sdb ) soffre di un lag pazzesco: se eseguo, ad esempio, smartctl --all sugli altri due mi salta subito fuori il risultato, mentre con il nuovo disco sono necessari ben 1 o 2 secondi!
Non capisco cosa possa essere! Dai log non si legge nulla se non

che riguardano il momento in cui ha perso il sync il disco che ho sostituito.
Ho altri 3 pc in cui è presente un raid crato allo stesso modo... funzionano tutti da più di 2 anni. Guarda caso l'unico che è in un ufficio è quello che da problemi.... maledetta legge di Murphy...
Boh non so che cavolo fare... sto cercando da tutte le parti, ma non ho ancora trovato nulla. Fortunatamente non usano il server dato che sono in vacanza, ma se continua così credo che l'unica cosa possa essere reinstallare tutto a partire da zero ( cosa che non mi auguro affatto ). |

uhm decisamente c'è qualcosa che non va...
hdparm -tT /dev/sda
| Code: |
/dev/sda:
Timing cached reads: 3276 MB in 2.00 seconds = 1638.32 MB/sec
Timing buffered disk reads: 258 MB in 3.01 seconds = 85.76 MB/sec
|
hdparm -tT /dev/sdb
| Code: |
/dev/sdb:
Timing cached reads: 3312 MB in 2.00 seconds = 1655.77 MB/sec
Timing buffered disk reads: 16 MB in 5.18 seconds = 3.09 MB/sec
|
Il problema è che /dev/sdb è il disco nuovo di pacca.... |
