Posted by NiTRo | Filed under VMware, ZFS

MAJ 23/05/2015 : Mise à jours des scripts pour exclure que les fichiers “.lck” (VSAN).

MAJ 30/10/2012 : Mise à jours des scripts pour n’exclure que les vm “invalid” ou “orphaned”.

MAJ 06/07/2012 : Mise à jour des scripts pour exclure “*/hostCache/*” pour ne pas remonter les fichiers vswp de la fonction Host Cache d’ESXi 5.

MAJ 05/07/2012 : Mise à jour des scripts pour intégrer les fichiers vswp.xxxxxx, merci à Larus Hjartarson pour l’idée.

MAJ 21/03/2012 : Mise à jour des scripts pour exclure “var/tmp/cache” dans le cas d’une redirection de la partition scratch sur un datastore.

MAJ 06/03/2012 : Mise à jour des scripts pour le support des multi-datacenter/multi-vcenter, des snapshot NetApp et des fichiers zdump qui trainent.


MAJ 28/02/2012 : Mise à jour des scripts suite à une erreur dans le “SideIndicator”

MAJ 24/02/2012 : Et pour ceux qui ont *VRAIMENT* confiance, voici le script pour supprimer les fichiers vswp orphelins (et si vraiment vous en avez, vous pouvez changer le filtrage au niveau du |?{$_.lostfile -match “vswp”}) :

foreach ($lost in (compare -passthru -property path $(foreach ($ds in ((get-view -ViewType datastore|sort name -unique|?{$_.summary.accessible}|%{(get-view $_.browser).SearchDatastoreSubFolders($("[" + $_.Name + "]"),(New-Object VMware.Vim.HostDatastoreBrowserSearchSpec -property @{matchPattern=("*zdump*","*.xml","*.vmsn","*.vmsd","*.vswp*", "*.vmx","*.vmdk","*.vmss","*.nvram","*.vmxf"); details=(New-Object VMware.Vim.FileQueryFlags -property @{filesize=$true;modification=$true})}))})|?{$_.file})){foreach ($files in $ds.file){$files|?{$_.Path -notmatch "-ctk.vmdk|esxconsole.vmdk|esxconsole-flat.vmdk"}|select @{n="path";e={$ds.FolderPath + $files.path|%{$_ -replace " ",""}}},FileSize,Modification|?{$_.path -notmatch ".zfs|.snapshot|var/tmp/cache|/hostCache/|.lck"}}}) $(get-view -ViewType virtualmachine|?{$_.Runtime.ConnectionState -notmatch "invalid|orphaned"}|%{$_.layoutex.file}|?{$_.type -ne "log"}|%{$_.name}|%{$_ -replace " ",""}|sort -unique|select @{n="path";e={$_}})|?{$_.SideIndicator -eq "<="}|select @{n="LostFile";e={$_.Path -replace "]","] "}}, @{n="FileSize";e={"{0:N0}" -f ($_.FileSize/1MB)}}, Modification|?{$_.lostfile -match "vswp"})){(get-view (Get-View ServiceInstance|select -first 1).content.filemanager|select -first 1).DeleteDatastoreFile($lost.LostFile,(Get-View -ViewType datacenter|?{$_.Datastore -match (get-datastore $lost.LostFile.split("[]")[1]|get-view).moref}|select -first 1).moref)}

MAJ 24/02/2012 : Mise à jour du script pour afficher la taille en MegaBytes et la date de modification des fichiers.

Très fortement inspiré du célèbre Raiders of the Lost VMX (mais aussi du post Orphaned files and folders – Spring cleaning) de LucD, nous avons enfin fini de finioler un oneliner PowerCLI qui va vous lister les fichiers .xml, .vmsn, .vmsd, .vswp, .vmx, .vmdk, .vmss, .nvram et .vmxf qui traînent sur vos datastores et qui ne sont pas rattachés à une quelconque vm du vcenter depuis lequel vous avez exécuté le script.

compare -passthru -property path $(foreach ($ds in ((get-view -ViewType datastore|sort name -unique|?{$_.summary.accessible}|%{(get-view $_.browser).SearchDatastoreSubFolders($("[" + $_.Name + "]"),(New-Object VMware.Vim.HostDatastoreBrowserSearchSpec -property @{matchPattern=("*zdump*","*.xml","*.vmsn","*.vmsd","*.vswp*", "*.vmx","*.vmdk","*.vmss","*.nvram","*.vmxf"); details=(New-Object VMware.Vim.FileQueryFlags -property @{filesize=$true;modification=$true})}))})|?{$_.file})){foreach ($files in $ds.file){$files|?{$_.Path -notmatch "-ctk.vmdk|esxconsole.vmdk|esxconsole-flat.vmdk"}|select @{n="path";e={$ds.FolderPath + $files.path|%{$_ -replace " ",""}}},FileSize,Modification|?{$_.path -notmatch ".zfs|.snapshot|var/tmp/cache|/hostCache/|.lck"}}}) $(get-view -ViewType virtualmachine|?{$_.Runtime.ConnectionState -notmatch "invalid|orphaned"}|%{$_.layoutex.file}|?{$_.type -ne "log"}|%{$_.name}|%{$_ -replace " ",""}|sort -unique|select @{n="path";e={$_}})|?{$_.SideIndicator -eq "<="}|select @{n="LostFile";e={$_.Path -replace "]","] "}}, @{n="FileSize";e={"{0:N0}" -f ($_.FileSize/1MB)}}, Modification|ft -autosize

Les snapshots ZFS (.zfs/snapshot), les fichiers -ctk.vmdk (fichiers CBT) et les vmdk des COS d’ESX classic (esxconsole-) sont filtrés, n’hésitez pas à nous remonter d’autres faux positifs que vous pourriez rencontrer. Prochaine étape : ménage automatique…

    Hi,

    The compare script works fine, and gave me this:

    Hi Jim, so what was the issue?

  5. Jim Nickel Says:
    August 27th, 2014 at 16:24

    I don’t know…I am hoping the author can fix it

    The problem has something to do with the parameters being passed to the DeleteDatastoreFile – the combination of the datastore and filename are not valid – wrong syntax or something.

    The compare script works fine.

    It’s just the delete script that doesn’t work.
