I began an update of one of our servers via yum and, coincidentally or not, I have been getting the following logged into the message file since: messages:Jan 7 15:55:51 inet07 kernel: post_create: setxattr failed, rc=28 (dev=dm-0 ino=280175) Now, this tells me that dev dm-0 is out of space but, what is dm-0? So, can anyone tell me what is happening and why? -- *** E-Mail is NOT a SECURE channel *** James B.

After finishing the update I ran yum clean and then rebooted the server. On startup the following were logged: Jan 7 16:43:39 inet07 kernel: EXT3-fs: INFO: recovery required on readonly file system. Jan 7 16:43:39 inet07 kernel: EXT3-fs: write access will be enabled during reco very. Jan 7 16:43:39 inet07 kernel: kjournald starting. Commit interval 5 seconds Jan 7 16:43:39 inet07 kernel: EXT3-fs: dm-0: orphan cleanup on readonly fs Jan 7 16:43:40 inet07 kernel: EXT3-fs: dm-0: 1 orphan inode deleted Jan 7 16:43:40 inet07 kernel: EXT3-fs: recovery complete. Jan 7 16:43:40 inet07 kernel: EXT3-fs: mounted filesystem with ordered data mod e. I would appreciate it very much if somebody could enlighten me as to what happened and why. Is this indicative of a hardware failure? Regards, -- *** E-Mail is NOT a SECURE channel *** James B.

I infer that dm-0 ===> VolGroup00-LogVol00 and that
VolGroup00-LogVol00 ===> /
so df / gives
# df /
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
8256952 6677880 1159644 86% /
I am guessing that the yum update caused the file system to fill and to
precipitate this problem. Is the the probable cause?
