Strani Errori sul server (error_log report)

[iettafune]

salve ragazzi, non capisco il motivo ma improvvisamente il mio vps ha smesso di funzionare. le pagine html le apre correttamente, ma appena vado nel forum si pianta dandomi errore, come se ci fosse un problema con il database mysql.

poi mi sono accorto che non mi si collegava più nemmeno all'ftp, poi dopo un po senza spiegazione si è collegato.

da virtuozzo non mi fa entrare in filemanager.

ho riavviato diverse volte il vps, provato a fare lo spegnimento e l'accensione.

niente da fare...

da plesk guardando i servizi attivi, vedo il servizio qmail stoppato, ma non riesco ad avviarlo!!

ho controllato l'error_log di apache e questo è il risultato..

come posso rimediare?

grazie

[Shazan]

Hai visto se qualche partizione si è riempita o se hai raggiunto il limite di inodes?

[iettafune]

guardando su virtuozzo risulta l'inodes pieno

Resource           Capacity     Total     Used     Available
Disk Space     43.58%     15.00 Gb     6.54 Gb     8.46 Gb
Disk Inodes     100.0%     200,000     200,000     0

dici che è quello il motivo??? come lo si libera quello spazio?? sono su un vps con centos 5.2, virtuozzo e plesk 8.6

[Shazan]

Certo che è quello.

Gli inodes occupati si liberano cancellando file, vedi un pò tu cosa puoi eliminare.

[iettafune]

sono su un vps....non posso eliminare nulla...di mio avrò circa 10GB occupati di roba... evidentemente quell'inodes è condiviso anche con gli altri utenti su questa macchina!!!!!

non c'è altro rimedio??

[Shazan]

Gli inodes riguardano il tuo VPS, non hanno niente di condiviso.

Anche se hai spazio libero, gli inodes si consumano in base al *numero* di file e non alla loro dimensione. Se con 10 GB hai finito gli inodes, significa che hai tantissimi file piccoli.

[iettafune]

purtroppo non capisco come possa esser possibile...questo problema mi si era già presentato un paio di mesi fa, quando inviai una mail globale a 80000 utenti... poi piano piano dopo aver avuto l'inodes al 100%, da solo e sceso ed è sempre stato sui 70 80 85%.... il problema è che mi sono riservati 200gb e se non sono in condivisione non capisco dove siano questi 200gb...

perchè del vps ho a disposizione 15gb in totale... sull'ftp ho solo 2.20gb, poi tra plesk virtuozzo ecc ne ho altri 3.XXgb comunque in totale sono sui 6gb circa...

questi 200gb di inodes dove diavolo si sono infilati??
settimana scorsa con il comando "du" ho sfogliato praticamente tutto alla ricerca di file grossi ma non ho trovato nessuna anomalia!!!

[Ste]

A questo punto potresti far alzare il limite di inode della vps, se non sbaglio in virtuozzo c'è una variabile da settare che lo consente.

[iettafune]

mmmm non ho mai sentito parlare di questa variabile modificabile in virtuozzo!!!

ma sinceramente non mi spiego dove siano realmente questi 200gb!!!

[Ste]

Ovviamente devi richiedere la modifica al provider direttamente dal pannello di Virtuozzo, se non sbaglio, virtuozzo è uno dei pochi che consente di aumentare il numero di inodes tenendo fisso lo spazio disco, Xen ad esempio dovrebbe comportare l'aumento dello spazio disco per aumentare gli inodes, aspetto conferma da altri però

[Shazan]

Non sono 200 GB, sono 200000 inodes.

[FlameNetworks]

iettafune è vero che siamo a Natale e siamo (dovremmo essere) tutti più buoni ma ora ogni volta che hai un problema sul tuo VPS vieni qui a 'piangere'?
Studia, studia, studia e studia...e POI vieni qui a chiedere aiuto. Oppure spendi qualche soldo e comprati un servizio managed.

Non me ne vogliate ma veramente non ce la posso fare più a leggere di questi thread.

[iettafune]

il forum è qui x questo...quando vedi il mio nick che apre un thread non entrare nemmeno x leggerlo

[iettafune]

Non sono 200 GB, sono 200000 inodes.

e non c'è un posto apposito dove stanziano?

[FlameNetworks]

iettafune questo non è un repository di sapere; ci sono delle guide online, se non hai voglia di studiare non venire qui a tediarci con queste domande.
