Question
Running the ioo command gives the following ioo: 1485-123 Error retrieving errors.
Cause
/proc is not mounted.
Answer
If /proc is not mounted running the ioo command will give output similar to the below example:
ioo: 1485-123 Error retrieving j2_inodeCacheSize: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_metadataCacheSize: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_nPagesPerWriteBehindCluster: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_maxRandomWrite: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_nRandomCluster: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_minPageReadAhead: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_maxPageReadAhead: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_nBufferPerPagerDevice: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_dynamicBufferPreallocation: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_maxUsableMaxTransfer: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_nonFatalCrashesSystem: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_syncModifiedMapped: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_atimeUpdateSymlink: A file or directory in the path name does not exist.
ioo: 1485-123 Error retrieving j2_syncdLogSyncInterval: A file or directory in the path name does not exist.
j2_atimeUpdateSymlink = 0
j2_dynamicBufferPreallocation = 0
j2_inodeCacheSize = 0
j2_maxPageReadAhead = 0
j2_maxRandomWrite = 0
j2_maxUsableMaxTransfer = 0
j2_metadataCacheSize = 0
j2_minPageReadAhead = 0
j2_nBufferPerPagerDevice = 0
j2_nPagesPerWriteBehindCluster = 0
j2_nRandomCluster = 0
j2_nonFatalCrashesSystem = 0
j2_syncModifiedMapped = 0
j2_syncdLogSyncInterval = 0
jfs_clread_enabled = 0
jfs_use_read_lock = 1
lvm_bufcnt = 9
maxpgahead = 8
maxrandwrt = 0
memory_frames = 65536
minpgahead = 2
numclust = 1
numfsbufs = 200
pd_npages = 65536
pgahd_scale_thresh = 0
pv_min_pbuf = 256
sync_release_ilock = 0
Note: The JFS2 values that give the error are still listed, but with values of 0.
1. To resolve the problem mount /proc by running the following command:
mount /proc
2. If /proc mount point does not exist, create it by running the following commands:
mkdir /proc
chmod 555 /proc
3. Check the /etc/filesystems file and ensure the following stanza exists:
/proc:
dev = /proc
vol = "/proc"
mount = true
check = false
free = false
vfs = procfs
4. Then mount /proc - see Step 1,
