probably gfs2 problem

We have a Mail Server (CentOS 6.5) with these component: - Postfix - Dovecot - Mysql - MailScanner (spamassassin,clamav) - GFS2 Partition Last night the server crashed and this is the kernel logs before that: May 11 01:07:01 mail1 kernel: original: gfs2_fallocate+0xdc/0x540 [gfs2] May 11 01:07:01 mail1 kernel: pid: 24608 May 11 01:07:01 mail1 kernel: lock type: 2 req lock state : 1 May 11 01:07:01 mail1 kernel: new: gfs2_fallocate+0xdc/0x540 [gfs2] May 11 01:07:01 mail1 kernel: pid: 24608 May 11 01:07:01 mail1 kernel: lock type: 2 req lock state : 1 May 11 01:07:01 mail1 kernel: G: s:EX n:2/28b165f5 f:yfIqob t:EX d:EX/0 a:1 v:0 r:4 m:200 May 11 01:07:01 mail1 kernel: H: s:EX f:W e:0 p:24608 [imap] gfs2_fallocate+0xdc/0x540 [gfs2] May 11 01:07:01 mail1 kernel: H: s:EX f:W e:0 p:24608 [imap] gfs2_fallocate+0xdc/0x540 [gfs2] May 11 01:07:01 mail1 kernel: H: s:EX f:W e:0 p:24608 [imap] gfs2_fallocate+0xdc/0x540 [gfs2] May 11 01:07:01 mail1 kernel: H: s:EX f:W e:0 p:24608 [imap] gfs2_fallocate+0xdc/0x540 [gfs2] May 11 01:07:01 mail1 kernel: H: s:EX f:W e:0 p:24608 [imap] gfs2_fallocate+0xdc/0x540 [gfs2] May 11 01:07:01 mail1 kernel: H: s:EX f:W e:0 p:24608 [imap] gfs2_fallocate+0xdc/0x540 [gfs2] May 11 01:07:01 mail1 kernel: H: s:EX f:W e:0 p:24608 [imap] gfs2_fallocate+0xdc/0x540 [gfs2] I found these solutions in this post titled: [/var/log/messages shows lines like "H: s:EX f:W e:0 p:19456 [imap] gfs2_fallocate+0xdc/0x540 [gfs2]" repeated many times and GFS2 file system becomes inaccessible in RHEL 6][1] but we're not a Red Hat subscriber. In the Dovecot logs I found the message: > MySQL server has gone away **NOTE:** Presently the MySQL data is stored on that GFS2 partition. Does anyone have any ideas on how to resolve this problem?
